Zabbix Mssql Failed To Fetch Info Data -or No Data For 30m- =link= Here

Then from (as the Zabbix agent service account):

user wants a long, detailed article about the Zabbix error "failed to fetch info data -or no data for 30m-" for MS SQL Server monitoring. I need to provide a comprehensive guide covering causes, diagnostics, and solutions. To do this, I need to gather information from various sources. I'll start with a broad search to get an overview of the issue and then follow up with more specific searches to cover different aspects. search results show some potentially useful links. I need to gather more specific information. I'll open the results that seem most relevant to the error message and the troubleshooting process. have gathered information from various sources. The search results cover the error message, troubleshooting steps, configuration best practices, ODBC setup, and known issues. I will now structure a comprehensive article that covers the following key sections: an introduction and context, common causes and error messages, prerequisites, macro configuration, ODBC driver setup, testing connectivity, instance name issues, troubleshooting, advanced topics, and a conclusion and recommendations. I will use the gathered information to support each section. error message is one of the most common and frustrating hurdles when setting up database monitoring in Zabbix, but it's also a signal that can guide you directly to the root cause. This article will decode what the message means and provide a complete, step-by-step guide to diagnosing and fixing the issue for good.

The monitoring user must have VIEW SERVER STATE (for SQL 2017/2019) or VIEW SERVER PERFORMANCE STATE (for SQL 2022). zabbix mssql failed to fetch info data -or no data for 30m-

Remember: Use the diagnostics in this guide to enforce a 15-minute maximum data outage, and set up proactive alerts for the monitoring system itself.

The error is one of the most common alerts faced by database administrators and DevOps engineers when configuring Microsoft SQL Server monitoring in Zabbix. This high-severity trigger fires when Zabbix fails to pull core operational metrics from your SQL Server database engine within a designated 30-minute interval. Then from (as the Zabbix agent service account):

The "MSSQL: Failed to fetch info data (or no data for 30m)" error is usually not a bug but a symptom of a missing dependency, misconfiguration, or permission issue. By systematically verifying the ODBC layer, the SQL Server permissions, the Zabbix macros, and the timeout settings, you can quickly restore full monitoring functionality. Regular testing using manual tools like isql and reviewing the Zabbix logs are the most effective ways to diagnose and prevent this error from recurring.

The errors “Failed to fetch info data” and “No data for 30m” in Zabbix MSSQL monitoring are symptoms of distinct underlying issues. The former is often permission or query-related; the latter points to timeouts or connectivity loss. A systematic diagnostic approach—starting with log analysis, manual ODBC testing, and MSSQL session inspection—enables rapid resolution. Implementing Zabbix Agent 2 and fine-tuning timeouts significantly reduces recurrence, ensuring reliable database observability.

Restart the Zabbix Agent 2 service to apply these changes. Common Troubleshooting Steps I'll start with a broad search to get

What appears when you hover over the red "info" icon next to the item in Zabbix?

Each UserParameter that runs a T-SQL query (like db.mssql.get from the official template) opens a new ODBC connection. If you have 5 databases × 30 items, the agent may exceed its Timeout setting (default 3 seconds) or ODBC connection pool limit.

Monitoring Microsoft SQL Server (MSSQL) with Zabbix provides critical insights into database health, performance, and availability. However, administrators frequently encounter a frustrating issue where Zabbix triggers an alert: or reports "No data for 30m" on key performance metrics.

This is a generic trigger often seen when using the "MSSQL by ODBC" or "MSSQL by Zabbix agent 2" templates. It indicates that the master "Info" item—which discovery and other dependent items rely on—is not receiving data. Core Causes & Fixes 1. Database Permissions (Most Common)
