Implementation
We wrote a script wrapper-_for-_hourly.pl to analyze the gathered raw ping data from the monitoring hosts and create the hourly aggregated data. The script enables one to select the metrics to be calculated, the time frame, the ping size and the host or site.
This was typically run as a batch job with the output shown here.
The output directory was of the form
| Code Block |
|---|
/nfs/slac/g/net/pinger/pingerreports/new/hep/maximum_rtt/maximum_rtt-100-by-node-1999-11-19.txt.gz
|
Note the "new". This enabled us to create all the aggregated reports for the selected metrics, check them out and then move or copy them to the regular file space, i.e. to:
| Code Block |
|---|
/nfs/slac/g/net/pinger/pingerreports/hep/maximum_rtt/maximum_rtt-100-by-node-1999-11-19.txt.gz
|
We also added these metrics to the pingtable.pl form.
