linux centos monitoring munin system-monitoring
We’ve installed munin monitoring on one of our servers. Generally it seems to be working well but occasionally, 4 times in 2 months to be exact, munin-cron has generated the following error:[FATAL] There is nothing to do here, since there are no nodes with any plugins. Please refer to http://munin-monitoring.org/wiki/FAQ_no_graphs at /usr/share/munin/munin-html line 38On searching for this error I can only find issues where munin is not working at all, rather than the intermittent problem that

munin dpkg
Server running Ubuntu 12.04 ltsI installed munin the other day on a server. I decided later to remove it with apt-get.I noticed that not everything was removed from the installation so manually removed the munin web directory and also removed the munin user-name and group from the sever.However I have just now tried to run apt-get upgrade which is now returning an error:dpkg: unrecoverable fatal error, aborting:syntax error: unknown user ‘munin’ in statoverride fileE: Sub-process /usr/bin/dpkg r

linux memory memcached munin
I’m looking into using memcached on our server. We’ve just upgraded and now have a fairly powerful box:DELL PowerEdge R710 Linux RHEL 5 – 64bit 12GB RAM(We used to be on a 32bit 4GB box).The problem is I am confused by how Linux actually uses memory and how this translates to my munin graph.So judging by my graph (or is there a handy command I can use in the console?) how much RAM can I safely assign to memcached. i.e how much RAM do I have spare?

munin
I have a munin setup running and I’d like to leave my munin-node setup untouched while getting a longer and more detailed view of the logged data. I want to keep all logged data indefinite. An ideal solution would use something like the Annotated Time Line widget so that I could zoom in to any point in the history.Edit: I’ve already found out that munin uses a lossy database so I’m expecting I’ll need something that replaces it; i.e. unless I’m mistaken, any answer that doesn’t replace Munin is

nagios munin monit cacti opennms
What would be the right management tool for my network? I take a look on Cacti, Nagios, OpenNMS, Munin & Monit … but I’m not sure which will be the best direction.I prefer something that will out of the box cover much as possible.I need to monitor: Router SNMP Switch SNMP 30 Server IPMI/SNMPServices like: nginx, unicorn, Tomcat, Jetty, MySQL, Elasticsearch, Hadoop, PHP, CometNice to have: Graphs for Bandwidth usage, nginx req/sec Any proposals?

linux lamp centos5 munin
I have a VPS on CentOS 5, running LAMP. Twice now in the last 3 months the server has had to be rebooted due to being out of memory. Downtime ends up being an hour, before someone can look at it. I have munin running to create some graphs, and am trying to figure out where to be looking (which logs) to find out what went wrong. There are some signs that it’s busy when the crash happens, but need more/better diagnosis. See the following munin graphs:Firewall and Disk are high just before the gap,

centos monitoring httpd munin monit
I’ve installed Munin and Monit on one of my servers running CentOS 5. Everything is working well, logging and reporting info, except for when the httpd process is restarted. I have Monit set to restart httpd if it hits 2.5gb of memory usage. If/when this happens, it’ll restart just fine, but Monit won’t pick up the new process.I’ll get a notice telling me that httpd service does not exist, and then another telling me httpd failed to start, and then a final one saying that the httpd service ti

monitoring logging syslog munin filter
Munin is quite verbose, and logs a bunch of things into munin-graph.log, munin-html.log, munin-limits.log and munin-update.log at each run of munin-cron.I already reduced munin-node logging level by setting log_level 0 in munin-node.conf, and that works well. munin-node.log only gets updated when an error message is generated.However I also tried to add the same option in munin.conf, but it makes munin crash.How one can reduce the amount of logs written by munin?

apache2 php cpu-usage munin
I have a web server: ubuntu apache+php app+postgresql and a stats server: ubuntu apache+php – piwik and munin2 installed.The communication for munin2 is made through ssh.In munin i see a lot of system cpu activity, that I assume it it because of apache (i see 5 or 6 apache instances using ~5% CPU on top)I was not having this system CPU activity before.Does anyone knows how can I see where that comes from?EDIT: some munin graphs
