Thanks Rick for checking  my request and for your response, I'm after understanding Auditd , As per my understanding Auditd provides more advanced logging  and it actually give you much more data insight in audit log than the standard logging which is enabled by default on the linux systems, not sure if my understand is correct here though? When we are pulling the data from a simple RHEL server using Splunk, we basically install a Splunk UF and push the TA_NIX app , which we use to basically collect everything under /var/log/* , now my understanding here is these logs that are under /var/log/* are the default logging setting on the linux which does not provides much of context on the log . for example who logged in , the username, the source IP address and the outcome which can only be achieved using Auditd rules. is it true ? Hope I was able to explain well this time, Appreciate if anyone can provide more insight on this. ... View more

Hello gcusello, Thanks for your inputs, However, like  I said the use case is I'm looking for IP that is causing maximum number of http errors(400s,500s) , lets say I'm trying to find a single IP that is causing  over 100 http errors . I think in the query we will have to use eval&case functions too. Please let me know if you need further clarifications on the above. Moh. ... View more

Hello GC, Thanks for your response and help , however, I still have a bit of confusion, where in this search I'm telling my dest_ip value from the indexed field should match my lookup field "blackip" value. And when you say your_key_filed is this the indexed field or the lookup fieldname, Lets take the 1st search you gave as example and please advise if this is any good and will show me the results as src,dst,port where dst should be only the one that are matched from my lookup table. index=fw [ | inputlookup blackip.csv | fields dest_ip ] | stats values(src_ip) values(dest_ip) by port     Thanks,     ...
