Hi !!
New to the list and to Graylog2 :)
I'm running a PoC on a VM and I started adding more nodes. The thing is
that at the top of the web page I can see the message: "Loading throughput"
and it never stops.
I also see that when I click on "Statistics" or "Quick values" or "Generate
chart" it takes for ever to show any result, even if it's a small query.
I imagine this is due to a HW limitation since I'm running my PoC on a VM
(VMWare) with 1 core, 8 GB of RAM and about 1 TB of storage. When I run
dstat (htop, top, ...) to see resource usage, I see:
CPU usage is low: 93% idle
RAM usage is high: 98% usaed
Swap usage: 0.45%
iostat gives me this ("a lot" of writes):
Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz
avgqu-sz await svctm %util
sdb 0.00 28.83 0.13 10.48 23.05 322.56 32.56
0.01 0.70 0.45 0.47
Right now I've got around 20 servers logging to this PoC: mainly NFS,
backup and Samba servers (all Linux). The idea would be to scale up to
around 100 servers + switches + storage arrays (probably 120 HW devices in
total). We seldom have a server spitting out log messages like crazy: some
NFS server misconfigured once in a while but nothing "out of the normal"
(if there is such thing as normal ;)
Graylog2 version is the latest available through the repos. Same with
MongoDB and elasticsearch.
OS is CentOS 6.7 also upgraded to the latest version. I can't upgrade to
7.x since it hasn't been "approved" internally :(
Reading through some docs, blogs, ... I see that some people recommend
hosting elastic search on a different physical node to Graylog2 (some
recommend 3 separate physical ES servers). I would like to know some of the
opinions around here of people with similar situations.
Thanks for any tips you an share with me ;)
