Server :: Munin Df Plugin - Volumes Missing On The Graph
Feb 23, 2011
I'm using munin to monitor our servers. Recently I created additional partitions on one of them and I noticed that munin has not picked up the changes.
I restarted munin-node and running the plugin manually as user munin on the machine
Code:
$ munin-run df
I get all my partitions
Also when I telnet 10.1.1.25 4949 and run
Code:
fetch df
I'm getting all of them. The graph however displays only the ones that were there at the time of munin install.
How can I get munin to add the new partitions to the graph ?
I downloaded a Munin plugin called "diskstats.in" [URL] but can't figure out how I'm supposed to run it. Have anyone here run this type of plugin before, and knows how to run it. It's written in perl, but running "perl diskstats.in" or "munin-run diskstats.in" results in error messages (let me know if you'd like the output from it
I need to monitor resource of my server.I have found munin and sysstat, Does munin use systat? or they are different package?because in some documents I have found on net,for installing munin, systat is needed !!for example on RedHat based distor, sysstat package is needed! but on debian is not needed
I am trying to solve a problem where Apache stats aren't displaying correctly in Munin. I've ran through quite a bit of checks and tests regarding Munin setup, but I think my issue is related to Apache, but my skill set there is lacking.
first, system info: monitored server: CentOS 5.3 2.6.18-128.1.1.el5
I have nagios and pnp4nagios installed and running fine. I have some snmp data that's monitoring an ASA5510.
I have the both the Data In and Data Out varibles, which go into individual graphs. Now I know that I can put the 2 data onto 1 graph, such as this graph: [URL]
I just don't know how to do it. I have in nagios the info here:
define host{ use WAN-devices ; Inherit default values from a template host_name firewall ; The name we're giving to this host alias firewall ; A longer name associated with the host address 10.x.x.x ; IP address of the host action_url /pnp4nagios/graph?host=$HOSTNAME$&srv=_HOST_ }
I installed MRTG some hours ago. Everything works fine (disk, cpu,..), except the network graph. For this graph, it's only work for ~3 cycles (15min), then... nothing.
This is the part of mrtg.cfg:
Code:
The number for eth0 is 3
Code:
SNMP is running:
Code:
Crontab is configured for mrtg (and seems it's not the problem because the other graphs works well):
Code:
In attachement is the graph for the memory (working!) and .. for the network, as you can see, only one small pic at the beginning.
I need to generate graph for Huawei AR4620 router . As I don't know the MIB for CPU USAGE I cannot create graph for CPU USAGE of Huawei Ar4620 Router. But I can create graph for Interface Traffic for Huawei AR4620 Router.
I am running Redhat linux 8.0 with 2.4.22 kernel. I am using this server for traffic shaping my static ip clients using tc. There are about 250 clients and I am running mrtg to monitor traffic via cronjobs each 5 minutes. When mrtg run I see too much packets loss in my network. What could be the problem in my server? RAM is 1gb and processor is Intel Pentium D 2.66GHz.
Recently I installed DEBIAN 6.0 amd64. Since then I have been unable to do netbanking (at least with linux) due to the missing 64bit java applet plugin, which does the authentication. I cannot get the 32bit plugin working with my browsers (epiphany, iceweasel).
Mozilla.org remmonds using a 32bit browser.
I then installed FIREFOX (32bit), however, it refuses to run : "unable to locate libgtk-x11..." to make it short: the library actually exists on my system (I located it), something else must be wrong.
My questions: will I be better off reinstalling the 32bit version of DEBIAN ? (or what about the possibility of a 64bit java applet plugin being released in near future- will this be wishful thinking or a realistic hope?) as a matter of fact, I have used the java applet since REDHAT version 5 or 6, a lot of years ago, so this plugin-trouble really takes me by surprise.
I installed an MP3 plugin, and tried to play a podcast on Rhythmbox, and was presented with an error message, which said: Your GStreamer installation is missing a plugin. How can I remedy this?
When I want to view in Mozilla this on line dictionary, it tells me that I have to install a missing plugin but it doesn't know which one. I can't view anything like that.
I have been asked to use space allocated to /dev/sdb2 to grow /dev/sdb1 both filesystems contain data. When I run lvdisplay or vgdisplay I get "no volume groups found". and pvdisplay returns nothing. Do I need to add the fs to a group?
I'm completely new to Fedora. I've tried using both Rhythmbox and Exaile to no avail. I keep getting a message that says "Playback error encountered! Your GStreamer installation is missing a plug-in." I have searched all over countless forums and blogs trying to figure out this issue. I went into add/remove software and searched GStreamer and basically checked everything that appeared to be what I needed, but that still hasn't worked. Insanely annoying not being able to play my music and even more annoying because I never had this issue with Ubuntu.
Just installed Clementine audio player, but it won't play mp4s. It says gstreamer is missing a plugin, google search turned up some leads but they didn't lead anywhere. Mp4s work fine in Amarok, and i have already installed the restricted extras package.
I am using xfce in squeeze and I like xfce4-governor-plugin. But this package is missing in debian, pls can you add this plugin to squeeze repository. xfce4-governor-plugin_0.1.0 works in squezze very well.
few days ago I upgraded amarok on my openSuSE 11.2 from amarok-2.3.1-1 to amarok-2.3.1-4 (with vendor change to OBS KDE:Backports obs://build.opensuse.org/KDE).Then I noticed that the lastfm service is not functioning. It was missing from the internet services as well. As if the plugin does not exist. Taking a look at the /usr/share/kde4/services I did not find any .desktop file that was referring to the lastfm service (as I found for magnitude or the other internet services in amarok). So I downgraded to 2.3.1-1 (vendor obs://build.opensuse.org/home:enzokiel).
After the downgrade I had the .desktop files, but still the lastfm plugin was not loaded. I checked the liblastfm and it was there:liblastfm.so -> liblastfm.so.0.3.1***ALAS*** it was the 0.3.1, not the 0.3.0 as it was required by the dependencies.A workaround I thought is to just make a symbolic link to the 0.3.1 with the name 0.3.0. So I did. And it worked. What didn't work is that when I upgraded back to amarok 2.3.1-4 the desktop files were still missing and so was the lastfm plugin from amarok internet services.
I share this for the following reasons:
1. Maybe other people have encountered the same problem, and this could save them time/effort
2. I don't know if I should open a bug report against this, or it is just a matter of how the package was compiled. I don't want to waste developer's time by investigating something that is not a bug, but a feature.__2a. I think this is an openSuSE specific problem, that is why I am posting it here.
3. Would the correct solution be a downgrade of both the liblastfm and amarok?
I'd like to get sync between evolution and nokia E51 running. Following the instructions given in [URL]
Therefore I need the plugin syncml-obex-client, but I cannot get it. I guess the problem is the that the package opensync-plugin-syncml cannot be downloaded.
I tried the "rpm", the "yum", and the "tar.gz" from the adobe site. Both rpms installed fine but I still can't view flash content in Firefox (missing plugin). The .tar.gz contained a .so file, but the installation instructions for the flash player said I should see an installer file in the .tar.gz, but I do not. I can't believe I can't even get flash player working. Their instructions said to check under "Help > About Plugins" but obviously Firefox does not and has never had such an option. I hate Adobe.
I'm setting up two media servers - one will be primary and the second will be the failover box if the first one dies. My original plan was to use Heartbeat and DRBD to replicate the first to the second, but it turns out DRBD has a limitation of 16TB per volume, and my RAID 6 is 30TB in size. I'm trying to figure out some options.
One is to split the partition into two, so it's under the 16TB limit of DRBD, share both partitions, and then use LVM to join them as a single volume at the OS level. I'm not sure what kind of performance hit that will make on read/write access since now it will need to go through LVM *and* DRBD.
Two is to use something like GlusterFS or XtreemFS. However, I am wary of both of those as the first is a FUSE-based system and isn't really tuned for performance, and XtreemFS is still kind of beta-ish.
Three is good old rsync, but that is a bit too asynchronous in my opinion. I'd like to be able to fail over virtually instantly and not lose any content.This is a production system and performance of the disk systems are paramount, followed by reliability.
I'm trying to make a fresh install of Ubuntu 10.10 Server 64bit but is stuck with the Partitioning Disk part and Ubuntu 10.04 LTS provides the same error. The installation wizard gives me a menu:
!! Partitioning disks This menu allows you to configure iSCSI volumes iSCSI configuration actions
We have a Centos 5.6 server mounting two iSCSI volumes from an HP P2000 storage array. Multipathd is also running, and this has been working well for the few months we have been using it. The two volumes presented to the server were created in LVM, and worked without problem.We had a requirement to reboot the server, and now the iSCSI volumes will no longer mount. From what I can tell, the iSCSI connection is working ok, as I can see the correct sessions, and if I run 'fdisk -l' I can see the iSCSI block devices, but the O/S isn't seeing the filesystems. Any LVM command does not show the volumes at all, and 'vgchange -a y' only lists the local boot volume, not the iSCSI volumes. My concern is that, the output of 'fdisk -l' says 'Disk /dev/xxx doesn't contain a valid partition table' for all the iSCSI devices. Research shows that performing the vgchange -a y command should automatically mount any VG's that aren't showing, but it doesn't work.
There's a lot of data on these iSCSI volumes, and I'm no LVM expert. I've read that some have had problems where LVM starts before iSCSI and things get a bit messed up, but I don't know if this is the case here (I can't tell), but if there's a way of switching this round that might help, I'm prepared to give it a go.There was absolutely no indication there were any problems with these volumes, so corruption is highly unlikely.
