Hi
can any tell me where does graylog store logs of client on base of rsyslog in centos
All log messages ingested by Graylog are indexed (and thus stored) in Elasticsearch.
location
can it be this (/var/log/elasticsearch/)
if i am stopping elasticsearch service , can i be able to see the logs or not and how can i restore the logs
Elasticsearch is a database, and in default it compress the logs, and may be store it in shards. so you can’t read the logs.
Here is the official Bacup and restore Doc.
https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-snapshots.html
If you make a snapshot, you also won’t see the logs. It is not an export tool/solution.
You might want to take a look at the Graylog Enterprise Archiving plugin:
http://docs.graylog.org/en/2.4/pages/archiving.html
What exactly do you want to know?
indices , document , and size concepts
how many size will it take and all vaule which are their
Shards and Replicas are terms from Elasticsearch, see https://www.elastic.co/guide/en/elasticsearch/reference/5.6/_basic_concepts.html#getting-started-shards-and-replicas for details.
The number of documents, indices, and the size on disk should be pretty self-explanatory.
Also make sure to read http://docs.graylog.org/en/2.4/pages/configuration/index_model.html for details about how Graylog is using Elasticsearch and what the concept of index sets means.
can u tell approx 15 to 20 linux and windows server logs required how much size on graylog server
No, a generic answer for that is not possible.
