FileIntegrityNodeStatus CR status types

These conditions are reported in the results array of the corresponding FileIntegrityNodeStatus CR status.

Succeeded - The integrity check passed; the files and directories covered by the AIDE check have not been modified since the database was last initialized.
Failed - The integrity check failed; some files or directories covered by the AIDE check have been modified since the database was last initialized.
Errored - The AIDE scanner encountered an internal error.

FileIntegrityNodeStatus CR success example

The following example shows a FileIntegrityNodeStatus CR with successful scan conditions.

Example output of a condition with a success status

[
  {
    "condition": "Succeeded",
    "lastProbeTime": "2020-09-15T12:45:57Z"
  }
]
[
  {
    "condition": "Succeeded",
    "lastProbeTime": "2020-09-15T12:46:03Z"
  }
]
[
  {
    "condition": "Succeeded",
    "lastProbeTime": "2020-09-15T12:45:48Z"
  }
]

In this case, all three scans succeeded and so far there are no other conditions.

FileIntegrityNodeStatus CR failure status example

To simulate a failure condition, modify one of the files AIDE tracks. For example, modify /etc/resolv.conf on one of the worker nodes:

$ oc debug node/ip-10-0-130-192.ec2.internal

Example output

Creating debug namespace/openshift-debug-node-ldfbj ...
Starting pod/ip-10-0-130-192ec2internal-debug ...
To use host binaries, run `chroot /host`
Pod IP: 10.0.130.192
If you don't see a command prompt, try pressing enter.
sh-4.2# echo "# integrity test" >> /host/etc/resolv.conf
sh-4.2# exit

Removing debug pod ...
Removing debug namespace/openshift-debug-node-ldfbj ...

After some time, the Failed condition is reported in the results array of the corresponding FileIntegrityNodeStatus object. The previous Succeeded condition is retained, which allows you to pinpoint the time the check failed.

$ oc get fileintegritynodestatuses.fileintegrity.openshift.io/worker-fileintegrity-ip-10-0-130-192.ec2.internal -ojsonpath='{.results}' | jq -r

Alternatively, if you are not mentioning the object name, run:

$ oc get fileintegritynodestatuses.fileintegrity.openshift.io -ojsonpath='{.items[*].results}' | jq

Example output

[
  {
    "condition": "Succeeded",
    "lastProbeTime": "2020-09-15T12:54:14Z"
  },
  {
    "condition": "Failed",
    "filesChanged": 1,
    "lastProbeTime": "2020-09-15T12:57:20Z",
    "resultConfigMapName": "aide-ds-worker-fileintegrity-ip-10-0-130-192.ec2.internal-failed",
    "resultConfigMapNamespace": "openshift-file-integrity"
  }
]

The Failed condition points to a config map that gives more details about what exactly failed and why:

$ oc describe cm aide-ds-worker-fileintegrity-ip-10-0-130-192.ec2.internal-failed

Example output

Due to the config map data size limit, AIDE logs over 1 MB are added to the failure config map as a base64-encoded gzip archive. Use the following command to extract the log:

$ oc get cm <failure-cm-name> -o json | jq -r '.data.integritylog' | base64 -d | gunzip

Compressed logs are indicated by the presence of a file-integrity.openshift.io/compressed annotation key in the config map.
