info report

The mgr:info report provides a high-level summary of Squid state, including the following information:

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.
