Summary indexing

Hi all,

Quick question about summary indexing:

I have this configuration in the savedsearches.conf

[esxtop_Group_Cpu_VM_SI]
action.summary_index = 1
action.summary_index._name = summary_vmware
cron_schedule = */5 * * * *
description = Summary index for esxtop_Group_Cpu (VM)
dispatch.earliest_time = -8m@m
dispatch.latest_time = -3m@m
displayview = flashtimeline
enableSched = 1
realtime_schedule = 0
request.ui_dispatch_view = flashtimeline
search = index="vmware" sourcetype="esxtop_Group_Cpu" | stats count by VM

After waiting for 5 minutes, I tried to search

index=”summary_vmware” source=”esxtop_Group_Cpu_VM_SI” | stats count by VM

But I’m seeing

VM      count
00, search_name=esxtop_Group_Cpu_VM_SI, search_now=1282431600.000, info_min_time=1282431120.000, info_max_time=1282431420.000, info_search_time=1282431632.311, VM="net-cdp.4238", count=55     1
00, search_name=esxtop_Group_Cpu_VM_SI, search_now=1282431600.000, info_min_time=1282431120.000, info_max_time=1282431420.000, info_search_time=1282431632.311, VM="net-cdp.4239", count=55     1
00, search_name=esxtop_Group_Cpu_VM_SI, search_now=1282431600.000, info_min_time=1282431120.000, info_max_time=1282431420.000, info_search_time=1282431632.311, VM="vmware-vmkauthd.4241", count=110    1
00, search_name=esxtop_Group_Cpu_VM_SI, search_now=1282431600.000, info_min_time=1282431120.000, info_max_time=1282431420.000, info_search_time=1282431632.311, VM="vobd.4230", count=55    1
00, search_name=esxtop_Group_Cpu_VM_SI, search_now=1282431600.000, info_min_time=1282431120.000, info_max_time=1282431420.000, info_search_time=1282431632.311, VM="vobd.4231", count=55    1
00, search_name=esxtop_Group_Cpu_VM_SI, search_now=1282431600.000, info_min_time=1282431120.000, info_max_time=1282431420.000, info_search_time=1282431632.311, VM=FT, count=110    1
00, search_name=esxtop_Group_Cpu_VM_SI, search_now=1282431600.000, info_min_time=1282431120.000, info_max_time=1282431420.000, info_search_time=1282431632.311, VM=LinuxTaskMemPool, count=110  1
...
...
...

How does the search string looks like to get the values of fieldname VM, eg VM="net-cdp.4238", VM="net-cdp.4239", VM="vmware-vmkauthd.4241", VM="vobd.4230", VM=FT

since

index=”summary_vmware” source=”esxtop_Group_Cpu_VM_SI” | stats count by VM

does not get the values of fieldname VM

It would be helpful if you showed up the original data you are summarizing over.

  • It seems to me that your quotes are wrong in your reporting query, but maybe that's from some copy/paste to here.
  • Also, either (the former is probably preferable):
    • Your summarizing search should use sistats instead of stats; or
    • Your reporting search should use sum(count) instead of count

Nevertheless, you should be getting a correct field extraction. Sometimes, the field extraction rules for summary data have been overridden, possibly because the sourcetype has been changed from stash, or some host-based or source-based rule takes precedence and prevents it from running right.

I will also note that your schedule will generate summaries over time ranges from

01:02:00 - 01:06:59
01:07:00 - 01:11:59
01:12:00 - 01:16:59
01:17:00 - 01:21:59
...
etc.

which while correct, are not particularly great if you wanted to aggregate or timechart up to 15min or 1h intervals typically on a quarter-hour or hour. Better to line them up on 5 minute markers by changing the cron to 3,8,13,18,23,28,33,38,43,48,53,58 * * * *
