Hello!
My webserver is running ubuntu 14.10 with elasticsearch 1.5.0 and java
1.7u55
For some reason,* the elasticsearch service often goes down,* resulting in
my website not being available to my users anymore (using FOSElasticaBundle
with symfony).
I am using systemctl to restart it automatically, but I would prefer a good
fix once and for all. I feel the logs I have are not descriptive enough.
Being pretty new to managing a server, I need some help.
Can someone help me figure out the reason for this failure ? What are the
right files I can output here to better understand the issue ?
Thanks !
*My systemctl status gives :*
elasticsearch.service - ElasticSearch
Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled)
Active: active (running) since Mon 2015-04-20 12:04:24 CEST; 1h 56min
ago <------------- Here it means restarted 1h56 ago. Why did it
fail in the first place ?
