How can I identity forwarder data rate and index data rate (to identify a lag and prioritize logs)?

[chintan_shah]

Hi,
Is there any way where we can identify how much data the forwarder is sending and how much data is being indexed in real-time?
The problem is that I have a single forwarder that is sending data to a single indexer and its sending multiple logs i.e. 50 monitored files with different indexes. I am receiving data from a few indexes in real time whereas for some indexes I am having a lag, so I want to remove the lag and if possible give higher preferences to some logs file.

For forwarder lag, start to look at the metrics.log on the forwarder, if you see that it is hitting a plateau of kbps speed, it may be that you are hitting the default thuput limit.

Also look at the timestamp, maybe is it a timezone issue.
