SQL Monitor 9

List of alerts

The Alert settings page lists all the alert types that SQL Monitor can raise.

Go to the Configuration tab. Under Alerts and metrics, select Alert settings:

Managing alerts

For each type of alert, you can:

  • disable it, so the alert will not be raised in future
  • change the level at which it is raised, to either low, medium, or high
  • change the thresholds that trigger the alert to be raised

You can edit the alert settings for a single SQL Server instance or across a number of instances at once (by creating a group). For job-related, disk-related or database-related alerts, you can edit the alert for a specific job, disk or database. 

When an alert is raised, you can quickly change its settings by clicking Configure alert in the Alert details page.

SQL Server specific alerts

SQL Monitor raises the following types of alerts for problems on a SQL Server instance or database:

Availability group - database not healthy

Raised when:

Any of the following conditions apply, for longer than the time you specify:

  • The replica database is not synchronizing
  • The replica database is not joined to the availability group, but the replica itself is joined
  • The replica database is not connected to the availability group, but the replica itself is connected
Configurable thresholds:Availability group database is not healthy for longer than x seconds/minutes/hours/days
Default settings:

Raised as High when a monitored availability group database is not healthy for longer than 30 seconds

Type:

Continuous

Automatically updated from Active to Ended when the condition that caused the alert to be raised no longer applies – in this case, when the database is healthy again.

Possible causes:
  • Suspended data movement
  • Database inaccessible
  • Delay caused by latency on the network
  • Delay caused by load on the primary or secondary replica

Availability group - failover

Raised when:The availability group fails over from a primary replica to a secondary replica
Configurable thresholds:None
Default settings:Raised as Medium
Type:

Event

Event alerts are raised for incidents that occur at a specific point in time; they do not change level, or update their status to Ended.

Possible causes:

Automatic failover occurs when the primary replica fails or goes offline for some reason. Planned manual failover and forced failover require initiation by a database administrator.

All three types of failover will cause this alert to be raised.

Availability group - listener offline

Raised when:The availability group listener is offline for longer than the time you specify
Configurable thresholds:Listener is offline for longer than x  seconds/minutes/hours/days
Default settings:Raised as High when a monitored availability group's listener is offline for longer than 30 seconds
Type:

Continuous

Automatically updated from  Active  to  Ended  when the condition that caused the alert to be raised no longer applies – in this case, when the listener is online again.

Possible causes:
  • The IP address of the listener is offline
  • There's a networking or cluster problem
  • The listener's port is no longer available

Availability group - not ready for automatic failover

Raised when:The failover mode of the primary replica is automatic, but no secondary replicas are configured for automatic failover, for longer than the time you specify
Configurable thresholds:Availability group is not healthy for longer than x  seconds/minutes/hours/days
Default settings:

Raised as Medium when a monitored availability group is not healthy for longer than 30 seconds

Type:

Continuous

Automatically updated from Active to Ended when the condition that caused the alert to be raised no longer applies – in this case, when the availability group replica is ready for automatic failover again.

Possible causes:The availability group is incorrectly configured. In order for a particular primary replica to fail over automatically when it fails or goes offline, the primary replica and target secondary replica must both be set to automatic failover mode.

Availability group - query slowdown on primary due to synchronous replication

Raised when:Synchronous replication causes query slowdown on the primary replica, resulting in the transaction delay exceeding a given threshold
Configurable thresholds:Transaction delay is greater than a specified value for longer than a specified time
Default settings:

Raised as Medium when the transaction delay is more than 10000 ms for longer than 120 seconds

Type:

Continuous

Automatically updated from Active to Ended when the condition that caused the alert to be raised no longer applies – in this case, when the transaction delay falls below the given threshold.

Possible causes:

In synchronous-commit mode, the primary replica doesn’t commit any transactions until it receives acknowledgement that all synchronous secondary replicas have finished hardening the commit in their log, resulting in transaction delay.

Several factors can affect transaction delay:

  • Flow control time
  • Log bytes received/sec
  • Log bytes flushed/sec (on the secondary replica)

Availability group - replica not healthy

Raised when:

Any of the following conditions apply, for longer than the time you specify:

  • The replica is not connected
  • The replica is not joined
  • The replica is not operational as a primary or secondary replica
Configurable thresholds:Replica not healthy for longer than x seconds/minutes/hours/days
Default settings:

Raised as High when a monitored availability replica is not healthy for longer than 30 seconds

Type:

Continuous

Automatically updated from Active to Ended when the condition that caused the alert to be raised no longer applies – in this case, when the availability group replica is healthy again.

Possible causes:
  • Mismatched encryption type or algorithm
  • Disconnected transport
  • Another application is using the connection port
  • The connection endpoint was deleted, or wasn't started

Availability group - replication falling behind

Raised when:The sum of the log send queue and the redo queue for a particular secondary replica has been exceeding a given threshold for longer than the time you specify
Configurable thresholds:Sum of log send queue and redo queue is greater than a specified value for longer than a specified time
Default settings:

Raised as Medium when the sum of the log send queue and the redo queue is more than 100 MB for longer than 120 seconds

Type:

Continuous

Automatically updated from Active to Ended when the condition that caused the alert to be raised no longer applies – in this case, when the sum of the log send queue and the redo queue falls below the given threshold.

Possible causes:
  • Slow network connection
  • The primary or secondary replica is overloaded, meaning transaction log records can't be sent
  • The secondary replica is experiencing resource problems, which increases the time it takes to redo the log entries received from the primary replica

Backup overdue

Raised when:

Either of the following conditions apply:

  • No entry for a full database backup of this database in the [msdb].[dbo].[backupset] system table.
  • The most recent entry for a full database backup of this database in the [msdb].[dbo].[backupset] system table is older than a specified time.

If a database belongs to an availability group, the alert is only raised on the copy of the database on the primary replica.   The alert is raised when all   entries for a full database backup for all copies of a particular database are older than the time threshold specified for the copy of the database that is on the primary replica.

Configurable thresholds:

Most recent backup is older than x seconds/minutes/hours/days

Default settings:

Raised as Medium when the last full backup is older than 7 days

Type:

Continuous

Continuous alerts can have multiple thresholds and are automatically updated from Active to Ended when the condition that caused the alert to be raised no longer applies - in this case, when a full backup is detected.

Possible causes:

  • No backup job scheduled.
  • Backup jobs not running or not completing. Check Job failing alerts on this SQL Server instance.
  • SQL Server Agent Service is not started - check for any SQL Server Agent Service status alerts.

Blocking process

Raised when:

A SQL process has been blocking one or more other processes for longer than a specified duration.

Configurable thresholds:

SQL process has been blocking one or more other processes for longer than x seconds/minutes/hours/days

Default settings:

Raised as Low when a SQL process has been blocking one or more other processes for longer than a total of 60 seconds

Type:

Continuous

Can have multiple thresholds applied and is automatically updated from Active to Ended when the condition that caused the alert to be raised no longer applies - in this case, when the block ends.

Possible causes:

  • Long-running queries.
  • Using Insert, Update or Delete on large numbers of records in a single transaction.
  • Canceling queries, but not rolling them back.

Cluster failover

Raised when:

The active node of a cluster changes to a different node.

Configurable thresholds:

None

Default settings:

Raised as Medium

Type:

Event

Event alerts are raised for incidents that occur at a specific point in time; they do not change level, or update their status to Ended.

Possible causes:

The previously active node has failed or been manually switched to a different node.

Database file usage

Raised when:

This alert has 3 configuration modes:

  • Percent Full: raised when space used in a database file is above a specified percentage.
  • Space Remaining: raised when the available space is less than a fixed amount.
  • Time Remaining: raised when the remaining time until the database file fills is less than a specified time.

Configurable thresholds:

  • Used database file space is more than x percent of the total file size.
  • Remaining database file space is less that x MB/GB.
  • Remaining time until the database file gets full is less than x days.

Default settings:

Raised as Medium when the remaining time until the database file gets full is less than 14 days.

This alert is disabled by default on master, model, msdb and tempdb as they are generally MBs in size and in most scenarios don't grow significantly, and on log files and tempdb as their growth patterns are not typically predictable based on historic growth.

Type:

Continuous

Possible causes:

Database file size is increasing.

Database unavailable

Raised when:

The database state is something other than Online, for longer than the time you specify

Configurable thresholds:

Database unavailable for longer than x seconds/minutes/hours/days

Default settings:

Raised as High when the database is unavailable for longer than 30 seconds

Type:

Continuous

Automatically updated from Active to Ended when the database state changes back to Online.

Possible causes:

Database has been manually removed, or has encountered a problem causing its state to change to Suspect, Emergency, Recovering or Restoring.

Deadlock

Raised when:

SQL deadlock is detected.

Configurable thresholds:

None

Default settings:

Raised as Medium

Type:

Event

Event alerts are raised for incidents that occur at a specific point in time; they do not change level, or update their status to Ended.

Possible causes:

  • Inefficient application code.
  • Application accesses objects in a different order each time.
  • User input during transactions.
  • Lengthy transactions.
  • Locks not being released as early as possible.

Deadlock trace flag disabled

Raised when:

SQL Monitor is unable to turn on the deadlock trace flag on a SQL Server instance (1204 for SQL Server 2000, 1222 for SQL Server 2005 and later). This means deadlock alerts can't be raised.

Configurable thresholds:

None

Default settings:

Raised as High

Type:

Continuous

Automatically updated from Active to Ended when SQL Monitor can enable the trace flag.

Possible causes:

Insufficient privileges for the account used to connect to the SQL Server instance.

SQL Monitor requires sysadmin permissions on this account to turn on the deadlock trace flag.

Differential backup overdue

Raised when:

Either of the following conditions apply:

  • No entry for a differential backup of this database in the [msdb].[dbo].[backupset] system table.
  • The most recent entry for a differential backup of this database in the [msdb].[dbo].[backupset] system table is older than a specified time.

If a database belongs to an availability group, the alert is only raised on the copy of the database on the primary replica. The alert is raised when all   entries for a differential backup for all copies of a particular database are older than the time threshold specified for the copy of the database that is on the primary replica.

Configurable thresholds:

Most recent backup is older than x seconds/minutes/hours/days

Default settings:

Alert is disabled by default

Type:

Continuous

Can have multiple thresholds applied and is automatically updated from Active to Ended when the condition that caused the alert to be raised no longer applies - in this case, when a differential backup is detected.

Possible causes:

  • No differential backup job scheduled.
  • Differential backup jobs not running or not completing. Check Job failing alerts on this SQL Server instance.
  • SQL Server Agent Service is not started - check for any SQL Server Agent Service status alerts.

Fragmented indexes

Raised when:

Both of the following conditions apply:

  • Fragmentation of one or more indexes in a database exceeds a percentage threshold.
  • The fragmented indexes contain more than a specified number of pages.

Configurable thresholds:

Percentage fragmentation level

Indexes contain more than x pages

Default settings:

Raised as Medium when index fragmentation is above 60% for indexes with more than 1000 pages

Type:

Continuous

Can have multiple thresholds applied and is automatically updated from Active to Ended when the condition that caused the alert to be raised no longer applies - in this case, when there are no fragmented indexes (based on the thresholds defined) for the database.

Possible causes:

Regular deleting or updating existing rows or values in a table.

Notes:

Checking for index fragmentation is a very resource-intensive activity.

For this reason, SQL Monitor only checks for fragmented indexes once a week: on Sunday 02:00.

This means that the alert may remain Active for some time after you fix the issue, and will only be updated after the next scheduled weekly check.

Integrity check overdue

Raised when:

Either of the following conditions apply:

  • No entry for an integrity check found following DBCC DBINFO WITH TABLERESULTS.
  • The most recent entry for an integrity check is older than a specified time.

Configurable thresholds:

Most recent integrity check is older than x seconds/minutes/hours/days

Default settings:

Alert is disabled by default

Type:

Continuous

Can have multiple thresholds applied and is automatically updated from Active to Ended when the condition that caused the alert to be raised no longer applies - in this case, when an integrity check of the database (DBCC CHECKDB) is detected.

Possible causes:

No integrity check has been carried out on a database, or the most recent integrity check was too long ago.

Job duration unusual

Raised when:

The job execution time is different from the baseline duration (the median of the last ten runs) by a specified percentage.

Configurable thresholds:

Percentage difference from baseline duration (either slower or quicker).

Ignore jobs with run times less than x seconds.

Default settings:

These defaults assume that once the baseline for a job is established, that job should not start running significantly more slowly or more quickly.

  • Raised as Low when duration is 50% different to baseline
  • Escalated to Medium when duration is 60% different to baseline
  • Escalated to High when duration is 70% different to baseline
  • Ignore jobs that run for less than 2 seconds.

Type:

Continuous

Can have multiple thresholds applied and is automatically updated from Active to Ended when the job next completes with a duration that is within the allowed percentage of the baseline duration.

Possible causes:

  • High system load
  • Sub-optimal SQL execution plan
  • Job is waiting on an event or blocked

Notes:

SQL Monitor calculates the baseline duration by using the job history to find the last ten run times.

SQL Monitor will not raise the Job duration unusual alert until the job history contains at least ten runs.

Job failing

Raised when:

Job does not complete successfully, and returns error code.

Configurable thresholds:

None

Default settings:

Raised as Medium

Type:

Continuous

Automatically updated from Active to Ended when the job runs successfully again, or when the job runs again and fails (in which case the original alert will be marked as Ended and a new alert will be raised).

Possible causes:

Check the Job outcome message for a raised alert to help determine the problem.

Log backup overdue

Raised when:

Either of the following conditions apply:

  • No entry for a transaction log backup of this database in the [msdb].[dbo].[backupset] system table.
  • The most recent entry for a transaction log backup of this database in the [msdb].[dbo].[backupset] system table is older than a specified time.

If a database belongs to an availability group, the alert is only raised on the copy of the database on the primary replica. The alert is raised when all   entries for a transaction log backup for all copies of a particular database are older than the time threshold specified for the copy of the database that is on the primary replica.

Configurable thresholds:

Most recent backup is older than x seconds/minutes/hours/days

Default settings:

Raised as Medium when the last log backup is older than 7 days

Type:

Continuous

Can have multiple thresholds applied and is automatically updated from Active to Ended when the condition that caused the alert to be raised no longer applies - in this case, when a transaction log backup is detected.

Possible causes:

  • No log backup job scheduled.
  • Log backup jobs not running or not completing. Check Job failing alerts on this SQL Server instance.
  • SQL Server Agent Service is not started - check for any SQL Server Agent Service status alerts.

Long-running query

Raised when:

Query has been running for longer than a specified duration.

Configurable thresholds:

Query duration is longer than x seconds/minutes/hours/days

Do not raise alerts for queries that contain certain strings (matching specified regular expressions).
