# Agents y modules generated by the plugin

The plugin will create one agent for each target database.

 Each agent will contain the following modules if "**engine\_uptime**" is activated:

<table border="1" id="bkmrk-restart_detection-pa" style="border-collapse: collapse; width: 100%;"><tbody><tr><td style="width: 50%;">restart\_detection</td><td style="width: 50%;">It will be 0 if an unexpected restart is detected, and 1 if this is not the case. When a server restarts unexpectedly, there can

be a disruption in database access, and potentially, transactions or data may not be saved correctly, leading to data integrity issues.

</td></tr></tbody></table>

If "**query\_stats**" is activated, each agent will contain the following modules:

<table border="1" id="bkmrk-queries-monitorizar-" style="border-collapse: collapse; width: 100%; height: 948px;"><tbody><tr style="height: 130px;"><td style="width: 50%; height: 130px;">queries</td><td style="width: 50%; height: 130px;">**The total number of queries**. Monitoring queries is essential for understanding the workload running on the server and assessing the overall system performance. By monitoring the total number of queries, you can identify activity spikes, optimize performance, and detect potential issues such as inefficient or excessive queries.</td></tr><tr style="height: 164px;"><td style="width: 50%; height: 164px;">update</td><td style="width: 50%; height: 164px;">**The number of UPDATE queries**. UPDATE queries are used to modify existing data in the database. Monitoring UPDATE queries is important to assess the frequency and efficiency of data updates. You can identify UPDATE queries that affect a large number of rows or have a significant impact on server performance. This allows you to optimize queries, review table structures, or take measures to reduce the load generated by updates.</td></tr><tr style="height: 164px;"><td style="width: 50%; height: 164px;">delete</td><td style="width: 50%; height: 164px;">**The number of DELETE queries**. DELETE queries are used to remove data from the database. Monitoring DELETE queries is useful to assess the frequency and efficiency of data deletions. You can identify DELETE queries that affect a large number of rows or have a significant impact on server performance. This allows you to optimize queries, review table structures, or take measures to reduce the load generated by deletions.</td></tr><tr style="height: 180px;"><td style="width: 50%; height: 180px;">insert</td><td style="width: 50%; height: 180px;">**The number of INSERT queries.** INSERT queries are used to add new data to the database. Monitoring INSERT queries allows you to assess the frequency and efficiency of data insertions. You can identify INSERT queries that are generating a high load on the server or may be causing performance issues. This enables you to optimize queries, review table structures, or consider strategies like deferred insertion to enhance performance in high-concurrency environments.</td></tr></tbody></table>

If "**analyze\_connections**" is activated, each agent will contain the following modules:

<table border="1" id="bkmrk-current-connections-" style="border-collapse: collapse; width: 100%;"><tbody><tr><td style="width: 50%;">session usage</td><td style="width: 50%;">**The number of current connections relative to the total maximum connections**. Monitoring session usage in SQL Server is important for optimizing performance, identifying locking issues, enhancing security and auditing, and efficiently planning server resources.</td></tr></tbody></table>

The plugin will also create one module for each custom query defined in the configuration file.
