🔗 info report
The mgr:info report provides a high-level summary of Squid state, including the following information:
| Â | Â | Â | Â |
|---|---|---|---|
| Field | Units | Meaning | SMP |
| UP Time | seconds | Current Time - Start Time | maximum among kid values |
| CPU Time | seconds | Total time spent using CPU during Squid process lifetime, including both user and system CPU time, as reported by getrusage(3). | sum of kid values |
| CPU Usage | % | CPU Time / UP Time. In other words, the portion of UP Time spent using CPU. | meaningless sum of kid values (bug) |
| CPU Usage, 5 minute avg | % | The portion of the last 5-minute interval spent using CPU. | meaningless sum of kid values (bug) |
| CPU Usage, 60 minute avg | % | The portion of the last 60-minute interval spent using CPU. | meaningless sum of kid values (bug) |
Interval-based stats are probably reported for the current (incomplete) interval if Squid has not been running long enough to report full interval stats.
