Hi @evslacker
We will need pcap file to get the raws logs to work on this issue. Could you please create a support ticket and attach the PCAP file there?

[evslacker]

Hi , I have not sanitized the pcap or I would say I'm not sure how to do that. pcap access will be only for the Splunk internal team right? and not public? Regards AK

Hi Ankit,

I checked the provided pcap file and tried a few logs from both of the files, but all the logs are being classified correctly. Could you please attach a screenshot of the Splunk event in the ticket? Please make sure to expand the event and then take the screenshot.
Also, if feasible, could you please point out the log that is not being classified correctly?

[evslacker]

Hello, Attached are the logs which are falling in the main index, as you can see fallback are incomplete logs. Everything is set up correctly from Zscaler Portal not sure, some logs are falling to correct dest and rest are here. [image: image.png] Note- That is PRE-13, used scrubbing, let me know if you need actual logs. Regards Ak

I cannot find the screenshot. If the data is sensitive, you can reopen the Splunk ticket 3577330 (if already closed) and attach the screenshot there.

[evslacker]

Check now, I directly pasted on emai earlier.

Hi Ankit,

I checked my email and the ticket 3577330 but couldn't locate the screenshot. It seems like the image wasn't attached properly as I only see [image: image.png].

Just for reference:

Could you please resend both the raw logs causing the issues and the screenshot of the Splunk events to my email address: cwadhwani@splunk.com?

Thanks!

[evslacker]

I have shared over email, can you check now. Regards AK

[cwadhwani-splunk]

Hi @evslacker
I checked the screenshot and it seems like the logs coming from the ZScaler are truncated. We can check this by obtaining the raw logs coming to SC4S.
Please create a support ticket if you need any help with this, the support team can assist you here to proceed with the case. If this has something to do with SC4S, feel free to add a comment/reopen this GitHub issue.

[evslacker]

I feel truncation is not an issue, as i could see logs in the correct index are between 1.5k to 2.5k Characters.

in the main index 1000-1900 max.

No Limits has been set in the sourcetype as well, so i would assume, it should be atleast 10k by default.

[evslacker]

is it possible to grab a TCPDUMP of only the logs which are not going to my index?

[cwadhwani-splunk]

I dont think that would be possible, not sure, but you can use <tcpdump command>| grep "<search_term>" to only get the udp packet content that contains the search_term. You can also try other method of obtaining raw logs, like using the sc4s-finalfilter and sending traffic the sc4s instance.

Please feel free to reach out to the support team for any help with this or to get the ZScaler config checked.
