MySQL Backup Status Test
Database backups are very important in an environment as these backups will help administrators recover the data at a faster pace in case of failures such database failures, system crashes, hardware failures or if users delete data accidentally. Backups are also essential as a safeguard before upgrading a MySQL installation, and they can be used to transfer a MySQL installation to another system or to set up replica servers. Frequent backup failures can cause data non-sync and increase the risk of data loss when disaster strikes. Therefore, it is essential for the administrators to closely monitor how well backups are performed in a MySQL installation. The MySQL Backup Status test helps in this regard!
This test helps administrators figure out the count of backups that failed and the count of backups that were completed successfully. In addition, this test reveals the count of backups that are currently running in the target environment. This test also helps administrators figure out the maximum time duration for a backup to be completed. Using the detailed diagnostics offered by this test, administrators can identify the backup type that is responsible for more backup failures.
Target of the test : A MySQL server
Agent deploying the test : An internal/remote agent
Outputs of the test : One set of results for the target database server instance being monitored
| Parameter | Description |
|---|---|
|
Test Period |
How often should the test be executed. |
|
Host |
The IP address of the MySQL server. |
|
Port |
The port at which the specified host listens. |
|
Database |
Specify the name of a database on the target MySQL database server being monitored |
|
Username and Password |
The eG agent has to be configured with the credentials of a user who has server-wide Process and Select privileges on the monitored MySQL server. To know how to create such a user, refer to Pre-requisites for Monitoring the MySQL Server |
|
Confirm Password |
Confirm the password by retyping it here. |
|
Maximum Duration |
In some environments, backups in the target MySQL database server may often take a few minutes and sometimes, take a few hours to complete. By default, a value of 0 is specified against this parameter indicating that the test will consider all backups executing on the target MySQL database server. However, if you wish to ignore a few regular backups that are completed within a specified time limit from the scope of monitoring, then, you can specify a value in minutes against this parameter. By doing so, this test will not collect information pertaining to the backups that are completed within the duration specified against this parameter. |
|
SSL |
Set this flag to Yes if the target MySQL database server that is to be monitored is SSL-enabled. By default, this flag is set to No. |
|
Detailed Diagnosis |
To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:
|
| Measurement | Description | Measurement Unit | Interpretation |
|---|---|---|---|
|
Successful backups |
Indicates the total number of backups that were successful. |
Number |
|
|
Failed backups |
Indicates the number of backups that failed. |
Number |
Use the detailed diagnosis of this measure to figure out the backup type that is failing more frequently. |
|
Running backups |
Indicates the number of backups that are currently running. |
Number |
The detailed diagnosis of this measure lists the Backup ID, Start time, End time, Duration(minutes), Binary log file, Backup type, Lock time, Backup state, Error message, Current backup time, Current Backup state and Backup state details. |
|
Maximum duration of successful backup |
Indicates the maximum time taken for a backup to complete successfully. |
Minutes |
The detailed diagnosis of this measure lists the Backup ID, Start time, End time, Duration(minutes), Binary log file, Backup type, Lock time, Backup state, Error message, Current backup time, Current Backup state and Backup state details. |
|
Total number of backups |
Indicates the total number of backups. |
Number |
If the number of backups are very high, administrators need to analyze and ensure the unused backups are deleted and disk space is reclaimed. |
The detailed diagnosis of the Failed backups measure lists the Backup ID, Start time, End time, Duration(minutes), Binary log file, Backup type, Lock time, Backup state, Error message, Current backup time, Current Backup state and Backup state details. Use the detailed diagnosis of this measure to figure out the backup type that is failing more frequently.
Figure 1 : The detailed diagnosis of the Failed backups measure
The detailed diagnosis of the Running backups measure lists the Backup ID, Start time, End time, Duration(minutes), Binary log file, Backup type, Lock time, Backup state, Error message, Current backup time, Current Backup state and Backup state details. Use the detailed diagnosis of this measure to figure out the exact name of the backups that are currently running.
Figure 2 : The detailed diagnosis of the Running backups measure
The detailed diagnosis of the Maximum duration of successful backup measure lists the Backup ID, Start time, End time, Duration(minutes), Binary log file, Backup type, Lock time, Backup state, Error message, Current backup time, Current Backup state and Backup state details. This helps administrators figure out the exact time taken by a backup to complete successfully.
