Logs WIndows to Splunk Cloud

adrifesa95 — Wed, 08 May 2024 16:50:22 GMT

Hello,

I have a problem because I can't see the windows logs in splunk cloud.

My architecture is as follows: UF->HF->Splunk cloud

I get the logs on the HF because I see them by doing packet inspection with tcpdump. So I have 9997 open, but these are not being forwarded to the cloud.

These are my inputs.conf

/opt/splunk/etc/apps/Splunk_TA_windows/local/ ###### OS Logs ###### [WinEventLog://Application] disabled = 0 index=mx_windows start_from = oldest current_only = 0 checkpointInterval = 5 renderXml=true [WinEventLog://Security] disabled = 0 index=mx_windows start_from = oldest current_only = 0 evt_resolve_ad_obj = 1 checkpointInterval = 5 blacklist1 = EventCode="4662" Message="Object Type:(?!\s*groupPolicyContainer)" blacklist2 = EventCode="566" Message="Object Type:(?!\s*groupPolicyContainer)" renderXml=true [WinEventLog://System] disabled = 0 index=mx_windows start_from = oldest current_only = 0 checkpointInterval = 5 renderXml=true ###### Forwarded WinEventLogs (WEF) ###### [WinEventLog://ForwardedEvents] disabled = 0 start_from = oldest current_only = 0 checkpointInterval = 5 ## The addon supports only XML format for the collection of WinEventLogs using WEF, hence do not change the below renderXml parameter to false. renderXml=true host=WinEventLogForwardHost index=mx_windows /opt/splunk/etc/system/local/inputs.conf [splunktcp://9997] index=mx_windows disabled = 0 [WinEventLog://ForwardedEvents] index=mx_windows disabled = 0

Hi @adrifesa95,

are you receiving Splunk internal logs from the HF and UFs in Splunk Cloud?

how did you configure the outputs.conf on the HF?

and on the UFs?

Ciao.

Well, it can be several things, network/config:

You have shown the inputs but what about the outputs?

Obviously, you will have a better understanding of your network / access / data flow details, but here's a number of area's for you to check and investigate.

Have you installed the Splunk Cloud UF App Package onto the HF (splunkclouduf.spl This contains the outputs.conf / TLS config, you download this from your Splunk cloud stack).
Have you allowed the HF for outbound connectivity to Splunk Cloud (Firewall changes) ?
After you download and install the Splunk Cloud UF App Package onto the HF, can you see the HF's _internal logs in Splunk cloud?
In Splunk cloud there is allow IP whitelisting feature, have you configured this for the HF to allow data to be sent to Splunk cloud?

Hello,

I answer to both of you, I leave you my outputs.conf that as you say I downloaded it from the cloud and it points to the indexers.

[root@host ~]# cat /opt/splunk/etc/system/local/outputs.conf
[tcpout]
defaultGroup = splunkcloud_20231028_9aaa4b04216cd9a0a4dc1eb274307fd1
useACK = true
indexAndForward = 0

[tcpout:splunkcloud_20231028_9aaa4b04216cd9a0a4dc1eb274307fd1]
server = inputs1.tenant.splunkcloud.com:9997, inputs2.tenant.splunkcloud.com:9997, inputs3.tenant.splunkcloud.com:9997, inputs4.tenant.splunkcloud.com:9997, inputs5.tenant.splunkcloud.com:9997, inputs6.tenant.splunkcloud.com:9997, inputs7.tenant.splunkcloud.com:9997, inputs8.tenant.splunkcloud.com:9997, inputs9.tenant.splunkcloud.com:9997, inputs10.tenant.splunkcloud.com:9997, inputs11.tenant.splunkcloud.com:9997, inputs12.tenant.splunkcloud.com:9997, inputs13.tenant.splunkcloud.com:9997, inputs14.tenant.splunkcloud.com:9997, inputs15.tenant.splunkcloud.com:9997

But this is a problem with this source, because I have other sources that go through that HF and arrive correctly to the cloud. I have already tested that port 9997 is up, but I must be missing something else. I have created the index mx_windows on both cloud and HF. any more ideas?

Hi @adrifesa95 ,

if your HF is forwarding other logs, te connection is ok.

so, try to remove the second stana in the inputs.conf of the HF leaving only:

[splunktcp://9997] disabled = 0

Ciao.

Sounds like order of precedence issue- These two will help in figuring out what is take the priority setting: (Some config is taking place before the other) but go by what @gcusello is saying.

Inputs config

/opt/splunk/bin/splunk btool inputs list --debug

outputs config

/opt/splunk/bin/splunk btool outputs list --debug

I have tried what @gcusello said, but it did not work.

Now I suspect that maybe they are not sending anything to the HF, because checking the connections with tcpdump to port 9997, I have seen that they are only with the splunk tenant. Can they use the same port to receive and make connections to the indexers (9997) and to receive logs from the UF (9997)? Do you recommend any other test?

Re: Logs WIndows to Splunk Cloud

You Windows Hosts should have an output.conf that sends to the HF only, if this is how you want your data flow architecture. (You don’t need the 100_tenant_splunkcloud installed on the Windows UF's Unless you want to send from them directly to Splunk cloud, this is also a viable solution.

I'm starting to think you may have the 100_tenant_splunkcloud and configured outputs to the HF on the Windows hosts, you need to have one or the other for this setup.

Run the btool outputs command on the Windows UF let’s see what that shows?

/opt/splunkforwarder/bin/splunk btool outputs list –debug

I should have said change to windows path as the command I gave is for Linux

Hi @adrifesa95 ,

it shouldn't be a probem: on your HF, you can receive logs on port 9997 and send logs to Splunk Cloud on 9997 port.

Check if from the UFs you can reach the HF (using e.g. telnet).

Ciao.
