we have installed 3 graylog server and 3 elastic server ( to manage and index the log) , in greylog we have also done mongo replication for graylog configuration and elastic search cluster is set to replicate indices
At a time we have one primary server which is responsible to save log in elastic server
But the data stored in this indices are not getting replicated to rest elastic server also the data in active cluster get compressed which is unable to be read by the graylog
we have also tried resync but were not successful
So our main requirement is to get data replicated in elastic search as well as for successful demonstration of traffic shifting between the 3 pair of graylog
The replication on Elasticsearch works perfectly fine if you have the right configuration set for the index.
On hitting _cat/health api on Elasticsearch, how many nodes cluster do you see? Sometimes the issue is when the nodes cannot join the cluster.
The data reading by greylog has nothing to with the data compression rate set on Elasticsearch.
It is done to save some hard disk space, generally 15% compression. It is not reading new data due to some connectivity issue or big refresh rate set in config.
Can I see your configuration settings and look for any issues.
