Microgateway Logs - stats line format

[mehedihashir-2]

These are 'stats' lines from the MIcroGateway logs. I havent found documentation on the apigee site on how to interpret these line. I did find documentation for other line types found in the logs.

Any ideas ?

Thanks - Mehedi

Some general points:

• There is one edgemicro process per CPU core (e.g. 4 in your example).
• These are logged every 60 seconds by each process, except for when there is no traffic in a 60s period. This explains why you see the stats log at pretty much the same second.
• They are incremental, until the process is restarted.

treqErrors

Total number of transaction requests which have failed.

tresErrors

This is never set.

statusCodes

Number of 1xx, 2xx, 3xx, 4xx, and 5xx status codes returned from target servers.

requests

Number of requests that have been processed successfully and sent to the target server.

responses

Number of responses received from target servers.

connections

This is bugged. It’s always undefined.

rss

rss stands for Resident Set Size, it is the total memory allocated for the process execution, in bytes.

cpu

The number of milliseconds each CPU has spent in user mode. (in the example, the CPU has 4 cores). This is not actually very useful by itself.
