huge values with tail plugin

Hi all,

I'm using the tail plugin to monitor exim traffic and ssh failed/invalid
login.
My configuration (see below) is pretty much the same as in the man page,
but from time to time I have huge values (last was 229.1M for "Local
delivered") in the RRD database.

Does anybody what could be causing this behaviour? Any problem in my config?

regards,
Manuel

P.S.: relevant part of my config:
<Plugin "tail">
        <File "/var/log/auth.log">
                Instance "Failed SSH attempts"
                <Match>
                        Regex "Failed password"
                        DSType "CounterInc"
                        Type "counter"
                        Instance "Failed password"
                </Match>
                <Match>
                        Regex "Failed password for invalid user"
                        DSType "CounterInc"
                        Type "counter"
                        Instance "Invalid users"
                </Match>
        </File>

Ruby seems popular for the task.  Back in the day I stumbled over
similar problems when I tried to setup Visage. If you feel like pursuing
the build problems this may come handy:

exec plugin stuck on mutex

We're seeing some strange behavior with the exec plugin. It works
great for a short period of time (usually a few hours) and then stops
reporting. I've also confirmed that the configured scripts are not
being exec'd once collectd gets into this funny state, so it appears
not to be a network/reporting problem, but a problem with the exec
plugin itself. All other aspects of collectd work fine while the exec
plugin is in this state.

Basic info:

    $ uname -a
    Linux fs5b.rs.github.com 2.6.26-2-amd64 #1 SMP Wed Aug 19 22:33:18
UTC 2009 x86_64 GNU/Linux

    $ collectd --help
    <snip>
    collectd 4.8.1, http://collectd.org/

Once I notice the plugin has stopped reporting, I have an extra
process (28489) hanging around:

    $ pstree -apu 22935
    collectdmon,22935 -P /var/run/collectdmon.pid -- -C
/etc/collectd/collectd.conf
      collectd,22936 -C /etc/collectd/collectd.conf -f
          collectd,28489 -C /etc/collectd/collectd.conf -f
          {collectd},22937
          {collectd},22938
          {collectd},22939
          {collectd},22940

SNMP Filtering

Hi,

In my network I have a several network devices (Cisco 7609) with over 
1000 interfaces (snmpwalk over ifTable returns more than 1000 indexes).
Most of them are VLAN interfaces, which I don't have to monitor.

Filtering using chains works perfectly, but the problem is huge number 
of snmpgets that overloads the CPU on the monitored devices.

So even though filtering mechanisam filters out all the unnecessary 
interfaces, snmp plugin still pools counters from all the interfaces, 
which results with CPU overload of monitored device.

Is there any solution to this problem ?

thanks
Domagoj

Collecting number of rows in a SNMP table (or similar)

Hi,

I'm new to collectd but I'm really optimistic that it might be a good
solution for our data-gathering needs.

I have not read all the documentation of all plugins etc but I have a
quick question:

I need to count the number of each interface type on our (100+) Cisco
switches and also the number of how many of these are populated by
fiber-optic modules and how many have their links up or down.

Today I do this by some ugly homemade collection scripts but they are
not very scalable when I in the future are gonna count routing tables
and other things.

PS: I don't need a detailed explanation of how to do this, just a Yes
or No, if there indeed is a way, I will (atleast try to) figure it out
for myself :)

Cheers,
Stian Øvrevåge

Is there a way to to BIND plugin workable ?

Hi there,

Sorry for my english.

Well, I am trying to load just BIND plugin. Doesn't work for me..

What I did :

- add this
statistics-channels { inet localhost port 8053; }; to my named.conf - add this <Plugin "bind"> URL "http://localhost:8053/"; OpCodes true QTypes true ServerStats true ZoneMaintStats true ResolverStats false MemoryStats true <View "_default"> QTypes true ResolverStats true CacheRRSets true Zone "127.in-addr.arpa/IN" </View> </Plugin> to collectd.conf add this : Loadplugin bind to collectd.conf too. I am on lenny, get the "collectdCould not find plugin bind." error message. Please, help me, 2 hours on that, I am becoming crazy.. Oh, /usr/lib/collectd/bind.so doesn't exist.. normal ?

If you're using the package on lenny, it should be version collectd 4.4,
the bind plugin is available since 4.6.
You should either compile a more recent version of collectd or install a
more recent package.

Thresholds

I'm getting started using thresholds with collectd and had a couple of
questions.

I see in the examples that you can use a Type for stuff like cpu, but
you need to use a Plugin for "memory" and "interface".  Is there any
set of base plugins that you can use without the Plugin tag or
something?

Also, I'm trying to do a threshold with df with a percentage and based
only on ext3 type filesystems.  I'm doing it like this currently:

<Type "df">
    Instance "ext3"
    Percentage true
    FailureMin 2
</Type>

I know it's a low number - I'm just trying to trigger a failure in the
log file.  Do I need to wrap the Type in a Plugin?  Is ext3 something
that needs to be an Instance or a DataSource?  I ask because even
taking out the Instance line, it doesn't trigger an error and I'm
pretty sure it should.

Thanks.

You could also try the lenny-backports version, which is 4.6.3. See
