Validate your configuration
To verify your SSL connections in Splunk Web, try the following command:
index=_internal source=*metrics.log* group=tcpin_connections | dedup hostname | table _time hostname version sourceIp destPort ssl
You can also splunkd.log to validate and troubleshoot your configuration. Splunkd.log is located on your indexer and forwarder at $SPLUNK_HOME/var/log/splunk/splunkd.log.
On the indexer, look for the following or similar messages at the start-up sequence to verify a successful connection:
02-06-2011 19:19:01.552 INFO TcpInputProc - using queueSize 1000 02-06-2011 19:19:01.552 INFO TcpInputProc - SSL cipherSuite=ALL:!aNULL:!eNULL:!LOW:!EXP: RC4+RSA:+HIGH:+MEDIUM 02-06-2011 19:19:01.552 INFO TcpInputProc - supporting SSL v2/v3 02-06-2011 19:19:01.555 INFO TcpInputProc - port 9997 is reserved for splunk 2 splunk (SSL) 02-06-2011 19:19:01.555 INFO TcpInputProc - Port 9997 is compressed 02-06-2011 19:19:01.556 INFO TcpInputProc - Registering metrics callback for: tcpin_connections
On the forwarder, look for the following or similar messages at the start-up sequence to verify a successful connection:
TcpOutputProc - Retrieving configuration from properties TcpOutputProc - Using SSL for server 10.1.12.112:9997, clientCert=/opt/splunk/etc/auth/server.pem TcpOutputProc - ALL Connections will use SSL with sslCipher= TcpOutputProc - initializing single connection with retry strategy for 10.1.12.112:9997
Below is how a successful connection might appear in splunkd.log on the indexer:
TcpInputProc - Connection in cooked mode from 10.1.12.111 TcpInputProc - Valid signature found TcpInputProc - Connection accepted from 10.1.12.111
Below is how a successful connection might appear in splunkd.log on the forwarder:
TcpOutputProc - attempting to connect to 10.1.12.112:9997... TcpOutputProc - Connected to 10.1.12.112:9997
You can also check metrics.log for something similar to the following:
index=_internal host=heavy hostname=universal | stats last(connectionType) as connectionType
For help troubleshooting your configuration issues, see Troubleshoot your forwarder to indexer configuration in this manual.
