Why is cmd script not running?

pbnl — Wed, 13 Apr 2022 15:13:06 GMT

hi all,

i try to run a cmd script on a UF. it's located in %SPLUNK_HOME%\etc\apps\log4jscan\bin\log4jscan.cmd and the content is
..\static\log4j2-scan.exe --all-drives --scan-log4j1 --scan-logback --csv-log-path "%SPLUNK_HOME%\var\log\log4jscan"

the inputs.conf is in %SPLUNK_HOME%\etc\apps\log4jscan\default and looks like this: (interval will be changed to run once per month)
[script://..\bin\log4jscan.cmd]
disabled = False
interval = 600

i added> debug.txt 2>&1 to the script, but no file is created.
any ideas?

thanks...

Does the log4j2-scan command work if run manually? Does Splunk have permission to run the command? Have you checked the UF's logs for messages that might explain why the script doesn't run?

after finding out that i have to change execprocessor logging mode to DEBUG, it shows, that the problem was with the path. after struggling around with that, i ended up with this:

inputs.conf
[script://$SPLUNK_HOME/etc/apps/PBNL_log4jscanWIN/bin/log4jscan.cmd]
disabled = False
interval = 15 0 1 * *
[monitor://C:\Program Files\SplunkUniversalForwarder\var\log\log4jscan.log]
disabled = false
sourcetype = log4jscan

log4jscan.cmd
"%SPLUNK_HOME%\etc\apps\PBNL_log4jscanWIN\static\log4j2-scan.exe" --all-drives --scan-log4j1 --scan-logback --csv-log-path "%SPLUNK_HOME%\var\log\log4jscan.log"

as you can see, it's a windows/linux mix of notation styles, where the monitor clause does'nt resolve variables.
from other posts i assuemed, the "base path" for an app is in my case %SPLUNK_HOME%\etc\apps\PBNL_log4jscanWIN\. but that seems to be not the case.

anyway, learned some new stuff...
