Monitoring Splunk

hosts reporting stats

I see there is a forwarder management dashboard in the monitoring console  where you can check if the host is reporting or not , I want the search that is used as the table contains the host name and the IP address , also there is no option for export in that dashboard , there is another similar dashboard in the monitoring console named forwarder_deployment but does not show the IP address only the host name , can you help with that ?

Hi @FAnalyst 

The answers provided so far look to either look at forwarders sending data to your Splunk indexers, or look at allowlist configurations in serverclasses, however I believe you are looking for the host and IP of deployment clients when they connect? If that is the case then try the below search:

 

| tstats latest(_time) as lastPhoneHome WHERE index=_dsphonehome earliest=-24h latest=now by data.clientId
| append 
    [| tstats latest(_time) as lastRestart where index=_dsclient earliest=0 latest=now by data.name, data.build, data.clientId, data.splunkVersion data.package, data.hostname]
    | stats latest(*) AS * by data.clientId
    | eval lastPhoneHomeFriendly=strftime(lastPhoneHome,"%d/%m/%Y %H:%M:%S")

This was tested on SPlunk 9.3 but I believe should work from <9.2

Please let me know how you get on and consider accepting this answer or adding karma this answer if it has helped.

You should be able to get list of whitelist servers using following query.

| rest /services/deployment/server/serverclasses | table title whitelist.* | untable title whitelist hostname | stats count by hostname | table hostname

You can put it to in a lookup file or just use the rest query itself and compare it against deployment/server/clients to know which clients that are configured in serverclass.conf but not sending phonehome. Something like this

| rest /services/deployment/server/serverclasses | table title whitelist.* | untable title whitelist hostname | stats count by hostname | table hostname | eval state="configured" | append [| rest /services/deployment/server/clients | table title | rename title as hostname | eval state="phonehome" ] | stats values(state) as state by hostname | where mvcount(state)=1 AND state="configured"

Use the below search to get an exportable list of deployment clients.

| rest splunk_server=local /services/deployment/server/clients 
| table hostname utsname
| sort utsname

Another way to find forwarders is to search the internal index for incoming TCP connections.

index=_internal sourcetype=splunkd component=Metrics group=tcpin_connections 
| dedup sourceHost
| table sourceHost fwdType

To see all hosts that send data, not just forwarders, count the hosts found in all indexes.

| tstats count where index=* host=* by host

thank you for your answer ,I tried the search you shared is does not show the IP  address of the hosts , also the number does not match the number showing in the forwarder management dashboard

Try this 

index=_internal sourcetype=splunkd component=Metrics group=tcpin_connections 
| dedup sourceHost
| table sourceHost fwdType

You can serch using following searches:

| tstats values(splunk_server) as Host, values(clientip) as IP
from _internal
where index=_internal sourcetype=splunkd
by host

or 

index=_internal sourcetype=splunkd
| stats values(clientip) as IP by host

Enjoy,
