Step 10 was to search for the following syntax:
| eval cmdlen=len(CommandLine)
| eventstats avg(cmdlen) as avg, stdev(cmdlen) as stdev by host
| stats max(cmdlen) as maxlen, values(avg) as avgperhost, values(stdev) as stdevperhost by host, CommandLine
| eval threshold = 4 * ( stdevperhost + avgperhost )
| where maxlen > threshold
Example returned an event with maxlen = 4490 but when I tried it on the "Launch Online Session" with the same search, I cannotfind that event.
I went to analyze the logs again and found that the maxlen is only 309. Step 1 to Step 9 were very accurate. What did I do wrong??
Hello again @wuming79. Your issue in the first screenshot above is that the "top" command is finding the "most prolific command line length values in the dataset" and NOT the "largest command line length value in the dataset."
