I'm running a summary index tracking event counts from a number of servers for each day.
I'm trying to put up a dashboard that tracks the number in events by day and by servers over the past 30 days. The search works fine, but when I try to chart this, the date format is all messed up because it only sorts on the day field of the time stamp.
index=summary source="summary-search earliest=-30d@d latest=@d | convert timeformat="%d/%m/%y" ctime(infomaxtime) AS Date | chart count over Date by orig_host
infomaxtime is an epoch timestamp,
I've tried various | sort options (time, Date, _indextime, infomax_time) after the chart command that all work in tables but not for charts.
Managers like pretty graphs and the US date format confuses them 🙂
Give this a try
index=summary source="summary-search earliest=-30d@d latest=@d | eval _time=info_max_time | timechart span=1d count by orig_host limit=0 | fieldformat _time=strftime(_time, "%d/%m/%y")
Thanks for the suggestion somesoni2. This sort of works but it always displays the first data point as Zero for all hosts and doesn't display the dates on the x -axis. If I can sort out the first data point issue, this should be fine for a dashboard.
you should try to create the chart before convert your date and after do the conversion, something like this:
yoursearch | bin infomaxtime span=1d| chart count over infomaxtime by host | eval _time=strftime(infomax_time,"%d/%m/%y")
Thanks Giuseppe, I had tried something similar myself, but its displays the epoch time on the graph instead of a date stamp, and this is for managers who wont understand epoch....
Also if i use "chart count over infomaxtime by orig_host" to show all the servers, it shows _time as a host and adds and extra line for it!! Any ideas why that might be happening?
but converting in back to a human form reverts to the original problem in that the ordering is wrong is UK date format.
The x axis is currently ordered on the first two digits so the months are out of order- ie
01/10/16 02/10/16 03/10/16 ...... 08/10/16 09/10/16 10/09/16 11/09/16 etc
Second answer - search is:
index=summary source="Summary - DC Daily Event Count" orighost=dc earliest=-30d@d latest=@d | convert timeformat=" %m/%d/%y" ctime(infomaxtime) AS Date | chart count over Date by orighost
There are a number of domain controllers and we run a summary search overnight for the previous days stats:
index=wineventlog source="WinEventLog:Security" host="DC" | sistats count by host
generates a summary index event like this:(_raw event)
10/07/2016 00:00:00 +0100, searchname="Summary - DC Daily Event Count", searchnow=1476090900.000, infomintime=1475794800.000, infomaxtime=1475881200.000, infosearchtime=1476090917.956, orighost=DCNAME, psrsvdgc=2389084, psrsvdv=1, EventCount="SummaryEventCount"
