Nagios Support Forum

Hi,

I am unable to start nagioslog server, I have start elasticsearch service many times, but it again goes down.

Can you share the contents of your Elasticsearch logs? Please zip up the following path and share them via an attachment:

No log is found at elasticsearch log location:

[root@localhost ~]# cd /var/log/elasticsearch/
[root@localhost elasticsearch]# ls
bc04b135-2d9b-4e73-9576-b17ec5b313c8_index_indexing_slowlog.log bc04b135-2d9b-4e73-9576-b17ec5b313c8.log

What happens if you try to start it? Please share the full output. How much ram / disk space did you allocate to the machine, and how many CPU's?

Service elasticsearch starts the service, but it alse went to down state with following error message.

[root@localhost ~]# service elasticsearch start
Starting elasticsearch: [ OK ]
[root@localhost ~]# service elasticsearch status
elasticsearch dead but pid file exists


Moreover machine specs are attached.

Thanks

I don't see any specs attached, could you please post them again?

PFA

This simply isn't enough resources for NLS. I would expand the processors to at least 2, and the memory to at least 8GB. As it's java based, the main requirement to use it is going to memory.

I increased resources and its start working for me.
Please close this thread.

Thanks
