I used to have a PaloAlto firewall and i had it setup to syslog on ump/5514. I was also running a couple of PaloAlto applications. I have retired the PaloAlto firewall and I uninstalled the apps via the "splunk remove app [appname] -auth :" command. I have recently installed a pFsense firewall in its place, and it to is setup to syslog via udp/5514. I am ingesting the new syslog data fine, but all of it is getting tagged with a source type of "pan:log". This is what the old PaloAlto data was tagged with so it worked with the PA applications. I have verified that my Data Inputs setting for udp/5514 is set to use a source type of "pfsense_syslog". Thus, something is overriding this. I have searched my system for a non-default transforms.conf, but all I see are the "default" examples.
Any ideas where I can look to determine what is causing this?
Can you check the output of
./splunk btool inputs list udp://5514 --debug? Or just
./splunk btool inputs list udp --debug
[splunker@n00bserver bin]$ ./splunk btool inputs list udp://5514 --debug /home/splunker/splunk/etc/apps/launcher/local/inputs.conf [udp://5514] /home/splunker/splunk/etc/system/default/inputs.conf _rcvbuf = 1572864 /home/splunker/splunk/etc/apps/launcher/local/inputs.conf connection_host = ip /home/splunker/splunk/etc/apps/Splunk_TA_windows/default/inputs.conf evt_dc_name = /home/splunker/splunk/etc/apps/Splunk_TA_windows/default/inputs.conf evt_dns_name = /home/splunker/splunk/etc/system/local/inputs.conf host = n00bserver /home/splunker/splunk/etc/system/default/inputs.conf index = default /home/splunker/splunk/etc/apps/launcher/local/inputs.conf source = syslog /home/splunker/splunk/etc/apps/launcher/local/inputs.conf sourcetype = syslog
Or in the GUI (if standalone) Settings > Data Inputs and check for the 5514 config.
That sourcetype is set in the inputs.conf, then the pan:log sourcetype is in the props.conf, which you can look for with
./splunk btool props pan:log --debug`
I assume that because its coming in on the same listener, it is simply applying the same settings??
Thanks for the suggestions mmodestino,
I tried all three suggestions, but nothing really grabs my attention:
# ./splunk btool props list pan:log --debug ==> no output # ./splunk btool inputs list udp://5514 --debug ==> no output # ./splunk btool inputs list udp --debug /Applications/Splunk/etc/system/default/inputs.conf [udp] /Applications/Splunk/etc/system/default/inputs.conf _rcvbuf = 1572864 /Applications/Splunk/etc/system/default/inputs.conf connection_host = ip /Applications/Splunk/etc/system/local/inputs.conf host = Jons-iMac.local /Applications/Splunk/etc/system/default/inputs.conf index = default /Applications/Splunk/etc/apps/TA-pfsense_a3sec/local/inputs.conf [udp://192.168.1.2:5514] /Applications/Splunk/etc/system/default/inputs.conf _rcvbuf = 1572864 /Applications/Splunk/etc/apps/TA-pfsense_a3sec/local/inputs.conf connection_host = ip /Applications/Splunk/etc/system/local/inputs.conf host = Jons-iMac.local /Applications/Splunk/etc/apps/TA-pfsense_a3sec/local/inputs.conf index = gw_pfsense /Applications/Splunk/etc/apps/TA-pfsense_a3sec/local/inputs.conf sourcetype = pfsense_syslog /Applications/Splunk/etc/apps/search/local/inputs.conf [udp://514] /Applications/Splunk/etc/system/default/inputs.conf _rcvbuf = 1572864 /Applications/Splunk/etc/apps/search/local/inputs.conf connection_host = ip /Applications/Splunk/etc/system/local/inputs.conf host = Jons-iMac.local /Applications/Splunk/etc/apps/search/local/inputs.conf index = main /Applications/Splunk/etc/apps/search/local/inputs.conf sourcetype = syslog # ./splunk btool props pan:log --debug Invalid command: pan:log
After restarting, it appears that the sourcetype is now correct. Odd that a restart was required. I would have thought that I would have been notified of a need to reboot when I uninstalled the applications. Oh well, all is well now. Thanks for the help!
ah nice! now I can sleep better at night! 😉
Good reference here regarding what config changes require restart, cause editing the conf files won't alert you to needing to restart...
