mesos-collectd-plugin
Hi, All,
Does anybody use this mesos-collectd-plugin:
https://github.com/rayrod2030/collectd-mesos
I have installed collectd and this plugin, then configured it as
instructions and restarted the collectd daemon, why seems nothing happens
on the mesos:5050 web UI( python plugin has been turned on in
collectd.conf).
My question is:
1. Should I install collectd and this mesos-collectd-plugin on each master
and slave nodes and restart collectd daemon? (This is what I have done.)
2. Should the config file mesos-master.conf only configured on master node
and
mesos-slave.conf only configured on slave node?(This is what I have
done.)
Or both of them should only appear on master node?
3. Is there an example( or a figure) of what output one is expected to see
by this plugin?
Cheers,
Dan

Can you just use the Mesos cluster name? We'd end up preferring that to a configuration tweak anyway.

Alright. You've convinced me I should put this online, but I'll have to
clean it up first. I would have originally but had one weird question.
In my company, we almost certainly will have multiple potentially large
Mesos clusters as different failure domains. The issue I've got is
relatively simple, the solution is not. The collectd daemon runs on every
single Mesos node (master or slave) in the firm. If it is running on a
master, it will get data from localhost:$master_port/metrics/snapshot. It
then checked if json_data["master/elected"] == 1 and ONLY reports the data
if it is the elected master. By default it uses a namespace like:
mesos.master.*
If you have multiple clusters this obviously won't work, so I added an
optional cluster name attribute to the collectd config. That way it will
report to:
mesos.archive.* where your mesos cluster name is "archive".
How would you propose a decent way to namespace master stats that are
cluster wide. I had to lie (in the collectd plugin code) and change the
host as a metric such as:
collectd.$HOSTNAME.master.* seems to make absolutely no sense when there is
a single elected master per cluster.

Hi, Jeff,
Thanks, is your plugin working together with collectd? It would be great
to publish it!
A general question for Mesos: Is there a method to monitor CPU/Memory/Disk
usages of jobs from different frameworks(e.g: Hadoop/Mapreduce, Spark etc)?
(Not necessarily to generate figures, text format numbers are quite enough.)
So e.g for a hadoop job, when it's finished, we can collect the general
metrics of it? Ideally although there are many jobs from different
frameworks running at the same time on mesos,
we still could get their metrics respectively.
Cheers,
Dan

I installed it and played with it for a bit but was somewhat underwhelmed
with it. It doesn't support slaves and all of the hardcoding with
duplication isn't my favorite. I ended up writing a single plugin to
support both masters and slaves and putting it on every node in my Mesos
cluster.
Would it be worth polishing up a bit and throwing on github?

I didn’t use it, but from the README.md, it is a collectd plugin, not mesos plugin. It pull mesos status into collectd world, not other way around. You won’t see anything on mesos UI, but you will have mesos metrics in collectd, which then you can leverage.

Hi, Dick,
1. Yes, /opt/collectd/etc/collectd.conf is my main and only collectd
config file.
2. Have put the <Module "mesos-master"> block into collectd.conf now.
3. I have set only 1 master, and set the Host line to ip address of
master node and restarted collectd.
I think I have to install graphite on my cluster too to let the following
line works in collectd.conf:
LoadPlugin write_graphite

Re: mesos-collectd-plugin

Hi Dan
I can see a couple of things that could be wrong
(NB: not a collectd expert, but these are differences I see from
my working config).
1. Is /opt/collectd/etc/collectd.conf your main collectd config file?
otherwise, it's not being read at all by collectd.
2. I configure the plugin in that file i.e. the
<Module "mesos-master">
block should be in /opt/collectd/etc/collectd.conf , not tucked down
in the python module path
directory.
3. Are you sure your master listens on localhost? Mine doesn't, I
needed to set that Host line
to match the IP I set that master to listen on ( e.g. in /etc/mesos-master/ip ).
Pretty sure one of those will do the trick
(NB: you'll only get metrics from the elected master; the 'standby'
masters still get polled
but collectd will ignore any data from them unless they're the primary)

Hi Dan
The .py files (the plugin) live in the collectd python path,
it sounds like maybe you're not loading the plugin .conf file into
your collectd config?
The output will depend on what your collectd is set to write to, I use
it with write_graphite.
