MSSQL by Zabbix agent 2
Overview
This template is designed for the effortless deployment of MSSQL monitoring by Zabbix via Zabbix agent 2 and doesn't require any external scripts.
Requirements
Zabbix version: 7.0 and higher.
Tested versions
This template has been tested on:
- Microsoft SQL, version 2019, 2022
Configuration
Zabbix should be configured according to the instructions in the Templates out of the box section.
Setup
-
Deploy Zabbix agent 2 with the MSSQL plugin. You can use this template starting with Zabbix versions 6.0.27 / 6.4.12. For more information, see MSSQL plugin documentation. Loadable plugin requires installation of a separate package or binary file or compilation from sources.
-
Create an MSSQL user for monitoring. For example, "zbx_monitor".
View Server State and View Any Definition permissions should be granted to the user.
Grant this user read permissions to the sysjobschedules
, sysjobhistory
, and sysjobs
tables.
For example, using T-SQL commands:
GRANT SELECT ON OBJECT::msdb.dbo.sysjobs TO zbx_monitor;
GRANT SELECT ON OBJECT::msdb.dbo.sysjobservers TO zbx_monitor;
GRANT SELECT ON OBJECT::msdb.dbo.sysjobactivity TO zbx_monitor;
GRANT EXECUTE ON OBJECT::msdb.dbo.agent_datetime TO zbx_monitor;
For more information, see MSSQL documentation:
Configure a User to Create and Manage SQL Server Agent Jobs
-
Set the username and password in the host macros
{$MSSQL.USER}
and{$MSSQL.PASSWORD}
. -
Set the connection string for the MSSQL instance in the
{$MSSQL.URI}
macro as a URI, such as<protocol://host:port>
, or specify the named session -<sessionname>
.
The Service's TCP port state
item uses the {$MSSQL.HOST}
and {$MSSQL.PORT}
macros to check the availability of the MSSQL instance, change these if necessary.
Note: You can use the context macros {$MSSQL.BACKUP_FULL.USED}
, {$MSSQL.BACKUP_LOG.USED}
, and {$MSSQL.BACKUP_DIFF.USED}
to disable backup age triggers for a certain database. If set to a value other than "1", the trigger expression for the backup age will not fire.

Get Buffer Manager counters | The item gets server information about the buffer pool. |
Dependent item | mssql.buffer_manager.raw Preprocessing

Auto-parameterization occurs when an instance of SQL Server tries to parameterize a Transact-SQL request by replacing some literals with parameters so that reuse of the resulting cached execution plan across multiple similar-looking requests is possible.

Dependent item | mssql.failed_autoparams_sec.rate Preprocessing
|
Safe auto-params per second | Number of safe auto-parameterization attempts per second. Safe refers to a determination that a cached execution plan can be shared between different similar-looking Transact-SQL statements. SQL Server makes many auto-parameterization attempts, some of which turn out to be safe and others fail. Note that auto-parameterizations are also known as simple parameterizations in the newer versions of SQL Server. This does not include forced parameterizations. |

Too frequently using pointers | Rows with VARCHAR columns can experience expansion when VARCHAR values are updated with a longer string. In the case where the row cannot fit in the existing page, the row migrates, and access to the row will traverse a pointer. This only happens on heaps (tables without clustered indexes). In cases where clustered indexes cannot be used, drop non-clustered indexes, build a clustered index to reorg pages and rows, drop the clustered index, then recreate non-clustered indexes. |
