Hi, we have two fields, latency and partition. I want to graph the latency vs. time on one of our machines for each of our partitions. So the resulting panel will have four separate line graphs. The log output we have is:
As you can see, there are 4 different partitions 00-BTECEU, 01-BTECEU, 02-BTECEU, 03-BTECEU. I was able to parse for the partition, but I'm having issues separating the latency for each partition.
Here's the query I tried, but the resulting table is empty:
host=irmnrjeb0227d AND latency | reverse | rex field=name "Partition\s(?<pName>\d\d\W\w+)" | streamstats current=f last(latency) as previouslatency by pName | rename latency as currentLatency | eval delta = currentLatency - previouslatency | timechart span=30s first(delta) as Delta by pName
Any help is appreciated, thanks!
If you are looking for the rex statement to extract both fields, then use this
| rex field=name "Partition\s(?<pName>\d\d\W\w+)\smax\slatency\s(?<latency>\d+)"
Note that the rename command is redundant, as you could use latency in the delta calculation
