Re: Graphite_Write and hostname

Wawrzek Niewodniczanski — 2013-05-21T11:08:42

Hi Dave,
[...]
Looks good.

Now need to check that following works with puppet.

FQDNLookup false
Hostname "<%= < at >hostname %>"


Thanks,
Wawrzek

Re: Graphite_Write and hostname

Dave Cottlehuber — 2013-05-21T10:35:04

Hi Wawrzek,

You can customise the hostname collectd uses like so in your conf file:

    FQDNLookup   false
    Hostname      "foo"

And if your host was called foo.bar.com before it will now use "foo"
instead. I guess this will also flow through to graphite as well.

A+
Dave

Graphite_Write and hostname

Wawrzek Niewodniczanski — 2013-05-21T10:23:56

Hi,

I'm setting up collectd with graphite as storage/presenting tool and
wonder if it possible to control 'hostname' format in the 'store'
path. Currently it is FQDN and I would prefer just hostname.

Thanks,
Wawrzek

Re: collectd Digest, Vol 92, Issue 14

kangqiang — 2013-05-20T04:33:40

Sorry, but I think you didn't understand my question. For example, I write a plugin use python as follows. I want to verify if my plugin would work,
then I run it. It cann't run because collectd can't import, the module is not exist.
I search in google, but every people say how to configure python plugin, not anywhere to say how to install python plugin dependency.
Below is some python code,error occured at the first line :


import collectd
import socket
from string import maketrans
from time import time
from traceback import format_exc


host = None
port = None
differentiate_values = False
differentiate_values_over_time = False
lowercase_metric_names = False
prefix = None
types = {}
postfix = None
host_separator = "_"
metric_separator = "."
protocol = "tcp"

Fwd: adsl monitoring via snmp

Phil White — 2013-05-18T21:29:48

Hi all,

I have recently obtained a new (for me) adsl terminal adapter - and would
rather like to keep an eye on it. The plan is to use snmp via collectd.
Unfortunately, it isn't quite working... Can anyone give me a hand?

Doing snmpwalk, I get (amongst other things) this:

IF-MIB::ifInOctets.1 = Counter32: 4192850
IF-MIB::ifInOctets.2 = Counter32: 0
IF-MIB::ifInOctets.3 = Counter32: 0
IF-MIB::ifInOctets.4 = Counter32: 63017231
IF-MIB::ifInOctets.5 = Counter32: 1000
IF-MIB::ifOutOctets.1 = Counter32: 58867993
IF-MIB::ifOutOctets.2 = Counter32: 0
IF-MIB::ifOutOctets.3 = Counter32: 0
IF-MIB::ifOutOctets.4 = Counter32: 2500412
IF-MIB::ifOutOctets.5 = Counter32: 1000

looking at the recipe at
https://collectd.org/wiki/index.php/Plugins:SNMP/Config I attempted to use
this:

<Plugin snmp>
    <Data "if">
       Type "if_octets"
       Table true
       Instance "IF-MIB::ifDescr"
       Values "IF-MIB::ifInOctets" "IF-MIB::ifOutOctets"
   </Data>

   <Host "gateway.local">
       Address "192.168.1.1"

Re: collectd Digest, Vol 92, Issue 9

Sven Trenkel — 2013-05-16T15:23:44

I'm really confused how this could happen, if there is any kind of error 
while initializing the collectd Python module then the entire Python 
plugin of collectd should refuse to continue and get unloaded by 
collectd so that it could never even launch the interactive interpreter.

So my only idea here would be:
1. Use the interactive mode in your config, as you have pasted it before.
2. Log all collectd messages to stdout
3. Do not load any other modules
4. Start collectd, try to import the module collectd
5. Past result here

The very short collectd config do do that looks something like this:

FQDNLookup   true
LoadPlugin logfile
<Plugin logfile>
         LogLevel info
         File STDOUT
         Timestamp true
</Plugin>
<LoadPlugin python>
         Globals true
</LoadPlugin>
<Plugin python>
         ModulePath "/path/to/somewhere/"
         LogTraces true
         Interactive true
</Plugin>

trouble building 5.2.2 with perl plugin

Russell Poyner — 2013-05-15T14:10:43

Has any one been able to build 5.2.2 on ubuntu 12.04 with the perl 
plugin? I have the current libperl-dev package installed.

There is an issue here: https://github.com/collectd/collectd/issues/310

Just wondered if anyone had some insight on this

[PATCH] exec plugin: Document that defaulting to PUTVAL is no longer done

At least, that's what the documentation at the end of this file says,

Hi again,

I was inspired to generalize what I was doing further to provide a 
MetadataFrom setting to be used like the ValuesFrom setting that names 
which columns to be added to the metadata:

I hope everyone will like this better.

I'm really appreciate for your replying, it is helpful to me.
Yes, I tried to import it in interactive interpreter, the

backtrace just say "no module named collectd". I can import time, os,system module, and can print it well.
hoping for your reply, thank you.

Re: collectd Digest, Vol 92, Issue 4

Sven Trenkel — 2013-05-11T21:34:52


The ModulePath certainly looks wrong (unless you actually have a 
directory called "libvirl_memory.py"), not sure if that might break 
imports, but probably not.
You're not actually importing a script you wrote so I'm assuming that 
you started "collectd -f" and are trying to write something from the 
interactive interpreter? In that case, does the failed "import collectd" 
command show any interesting backtrace? Do other imports work? Please 
try one normal python module (like "time") and one script you wrote 
yourself (doesn't have to do anything, just print "Hello world" would be 
enough to see if it works).

Re: Linux Proces Monitoring With Collectd & Graphite

Florian Forster — 2013-05-10T08:39:23

No, you can repeat the "Process" and "ProcessMatch" options in the
block, e.g.:

  <Plugin "processes">
    Process "foo"
    Process "bar"
    ProcessMatch "qux.* --interesting=true"
  </Plugin>


For "selected" processes (i.e. those matching Process{,Match}) it
collects the Resident Segment Size, which is approximately the physical
memory used by the process. Virtual memory size is currently not
submitted, I think.

amit shah — 2013-05-10T08:33:38

The processes plugin gets RSS and that should be be the amount of memory
used by the process (second question)?

Re: Linux Proces Monitoring With Collectd & Graphite

Few follow up questions.
1. So to collect statistics for different processes I would have to include
multiple <Plugin processes> in the conf file?

2. The processes plugin captures cpu usage along with other statistics. How
do I gather memory statistics for specific processes?

Thanks!

I also just mergd the "cgroups" plugin into the master branch. With it

hi,
    it seems it's not about config. When I write python plugin, i first need to import collectd. I tried to import it in ipython, it throws exception.
    anyway, my python collectd config as follows:
<Plugin python>
        ModulePath "/opt/monitor/libvirt_memory.py"
        LogTraces true
        Interactive true
#       Import "spam"
#
#       <Module spam>
#               spam "wonderful" "lovely"
#       </Module>
</Plugin>

[PATCH] Annotate database meta data

Mark Wong — 2013-05-09T19:33:19

Hi everyone,

If anyone was interested in the postgresql plugin patch I posted a 
couple years back 
(http://mailman.verplant.org/pipermail/collectd/2011-January/004341.html) to 
put the things like table and index names in the meta data, I finally 
got back to making another pass at it.  I think I'm doing it a little 
smarter than before and I wonder if doing it this way will work with the 
other database plugins now.  I've tried it only against 5.2 so far:

https://github.com/mwongatemma/collectd/commit/14bb87bd1b282340f4c49edf6c2f0f9a1b7addbd

Please let me know if you have any questions or comments.

Thanks,
Mark
