Hello,

I have problem with Splunk Forwarder.

Currently, i monitor a dir (/var/log/httpd/*) but it automatic delete old log and insert new log. Index default is "main".

I want to store with new index name "weblog", i have do:
- Step 1: delete all log httpd with search query: "source=httpd | delete"
- Step 2: remove old monitoring and add new: ./splunk add monitor "/var/log/httpd/*" -index weblog -sourcetype newsource

But it not working.

I use command below it working but not define new index: ./splunk add monitor "/var/log/httpd/*" -sourcetype newsource

Can you help me resolve my problem?
Thanks.

Hi tanglong,
when you already ingested logs from a file you cannot ingest them again, also renaming the file.
To do this you have to use a workaround:

  • delete the old logs from the main index using the delete command, remember that only special users (can_delete role) can delete logs, this step isn't mandatory;
  • create the new index weblog on Indexer
  • modify inputs.conf on Forwarder adding the option index = weblog to inputs.conf;
  • modify inputs.conf on Forwarder adding the option crcSalt = <SOURCE> to inputs.conf;
  • restart Forwarder;
  • after the logs are reindexed delete the crcSalt = <SOURCE> row from inputs.conf and restart Forwarder.

In this way logs are reindexed and sent to the new index.

Remember that if you add the can_delete role to you admin user, it's a good idea disable this feature as soon as after the deletion, it isn't a good idea to have this feature enabled.

Bye.

The fishbucket on the forwarder will remember that this file has already been forwarded and will refuse to forward it again. You can either:
1: Clear the fishbucket for this file.
2: Manually send the file using splunk add oneshot.
Also, do not use the CLI to configure ANYTHING in Splunk. You should create your own forwarder app and put your configurations in that.
