ES timestamp from logstash collectd codec

Elastic Stack Logstash
1

I'm following the link below to set up the collectd and logstash while storing the data in the ES.

https://www.elastic.co/guide/en/logstash/current/plugins-codecs-collectd.html

Just wondering what does the timestamp in ES represent? Is it time being loaded to ES? Can I use the time when the collectd collected or sent the data or something like that?

Thanks.

The @timestamp field is the event timestamp from collectd. The codec does all of the translation for you.

That's great! And thanks for sharing the exact code for that.

I asked this question as I use elastalert to query the events I found sometimes the elastalert responds with less hits than the count I can find from ES within the same query window. I came to know query_delay option of the rule but wondering if there is any other option to take. Thinking how to to speed up the indexing time to ES.

Thanks!

That's a different question altogether. To preserve this thread as collectd-specific, I ask that you launch a new discussion, or find one of the many excellent ones on that topic.

Okay, appreciate your help!
