| Test |
Duration |
Result |
| CPU load is computed from /proc/stat deltas, so the first sample has no CPU metric yet |
0.030s |
passed |
| RAM comes from MemTotal and MemAvailable in GiB |
0.002s |
passed |
| a changed disk source restarts the disk series and keeps the others |
0.027s |
passed |
| a corrupt state file starts a fresh series instead of failing |
0.004s |
passed |
| a failing quota command degrades to the volume, logged once, the sample still succeeds |
0.006s |
passed |
| a group quota on the repository's filesystem replaces the file-store disk numbers |
0.005s |
passed |
| a restart loads the persisted aggregation state and continues the series |
0.015s |
passed |
| disk and repository size are reported in GiB |
0.003s |
passed |
| min, max, and avg aggregate over all samples |
0.012s |
passed |
| the repository size probe is throttled to every 10th sample |
0.014s |
passed |
| the snapshot before the first sample is empty but well-formed |
0.001s |
passed |
| unreadable sources degrade to null metrics, never fail the sample |
0.005s |
passed |
