Chapter 106. Checking disk space using IdM Healthcheck
You can monitor the Identity Management server’s free disk space using the Healthcheck tool.
For details, see Healthcheck in IdM.
Prerequisites
- The Healthcheck tool is only available on RHEL 8.1 and newer.
106.1. Disk space healthcheck test
The Healthcheck tool includes a test for checking available disk space. Insufficient free disk space can cause issues with:
- Logging
- Execution
- Backups
The test checks the following paths:
| Paths checked by the test | Minimal disk space in MB |
|---|---|
|
| 1024 |
|
| 512 |
|
| 1024 |
|
| 512 |
|
| 512 |
|
| 512 |
To list all tests, run the ipa-healthcheck with the --list-sources option:
# ipa-healthcheck --list-sources
You can find the file system space check test under the ipahealthcheck.system.filesystemspace source:
- FileSystemSpaceCheck
This test checks available disk space in the following ways:
- The minimum raw free bytes needed.
- The percentage — the minimum free disk space is hardcoded to 20%.
106.2. Screening disk space using the healthcheck tool
Follow this procedure to run a standalone manual test of available disk space on an Identity Management (IdM) server using the Healthcheck tool.
Since Healthcheck includes many tests, you can narrow the results by:
-
Excluding all successful test:
--failures-only -
Including only space check tests:
--source=ipahealthcheck.system.filesystemspace
Procedure
To run Healthcheck with warnings, errors and critical issues regarding available disk space, enter:
# ipa-healthcheck --source=ipahealthcheck.system.filesystemspace --failures-only
A successful test displays empty brackets:
[]
As an example, a failed test can display:
{
"source": "ipahealthcheck.system.filesystemspace",
"check": "FileSystemSpaceCheck",
"result": "ERROR",
"kw": {
"msg": "/var/lib/dirsrv: free space under threshold: 0 MiB < 1024 MiB",
"store": "/var/lib/dirsrv",
"free_space": 0,
"threshold": 1024
}
}
The failed test informs you that the /var/lib/dirsrv directory has run out of space.
