Munin was running OK on my cPanel server until yesterday when the graphs stopped updating themselves. I attempted a "/usr/share/munin/munin-update --force-root" which did nothing. Then I uninstalled and reinstalled munin on the cPanel plugins screen and now its running but all the graphs are empty
View 3 Repliesif you can dump the actual data used to make the graphs in munin, or are the graphs the only way to view the data?
View 2 Replies View RelatedI have ~50 megabits of data connectivity and about ~10 servers connected to it at any given time. I want to start monitoring BW stats at the switch level for each machine. What is needed to set this up A to Z
I know i need a switch that is capable of SNMP I believe. Anyone have any recommendations on which switch to purchase ( i am looking for a 12-24 port switch) Midrange on prices on what to expect.
Once i have the switch in place from there what needs to be done in order to start producing graphs on a per server basis?
I've never setup a bandwidth monitoring system before, as we've really only used the datacenter supplied MRTG, PRTG, or RTG graphs for our cabinets until now.
I'm curious what solutions different users out there use; why you use them; and what you like/dislike about those systems.
i'm runing a plesk server... anyone knows a good/simple way to install a graphs system for analyze server numbers?
I have found Cacti and Cricket...
I think Cacti is easier to install but it's still complicated...
I would like to see graphs of load average, memory, but ALSO httpd connections, httpd average response, mysql threads, ...
Can you guys recommend a server by looking at the graphs below?
Connections „ CPU Usage „ Load Average
Memory Utilization „ Swap Memory „ Traffic
I'm trying to identify the right hardware for the job without going overkill with the specs, as the budget is limited.

/var keeps getting filled up with munin logs. Do I really need these logs? The server already had munin when I got it so I don't know how it was installed.
Can I disable it? I looked at the cron tab, and I don't see munin, but when I did chkconfig --list I found:
munin-node 0: off 1: off 2: on 3: on 4: on 5: on 6: off (spaces added because it made smileys)
How do I disable it?

Install Complete (munin 1.2.4)
Done
I did some googling about the error and it is because rrdtool is not installed.
Actually i installed rrdtool 1.3.0 from its website it was in /usr/local/rrdtool
Anyway i clicked install a rpm from whm and choose rrdtool.i386
root@server # rpm -qa | grep rrd
rrdtool-1.2.23-6.fc6
But it is still giving error above when i try to install munin
I use Munin to monitor the health of our servers, I can tell by looking at the graphs there's nothing to worry about, however, I'm struggling to baseline acceptable performance.what would be classed as 'normal' output for some of the more relevant munin graphs.
I've been looking at the Apache* modules and this is the output from one of our servers:
average of: 300 accesses per minute, 6 busy servers and 4.10MB a minute volume
max of: 1400 accesses per minute, 81 busy servers and 51MB a minute volume
This is a dedicated box running one site.
We have another box that is running approximately 30 sites
average of: 30 accesses per minute, 1 busy server and a 500K a minute volume
max of: 322 accesses per minute, 11 busy servers and a 4MB a minute volume.
These servers are pretty much the same spec, dual core 64Bit, 4GB of ram, two SATA disks in RAID1.
I'm checking my CPU/Memory/MySQL Usage and I'm seeing that something called Munin is running at 54%. That is apparently the average for today. Can anyone give me any insight as to what this is?
Wikipedia classifies Munin as a network monitoring application. I don't think it should be using this much processing.
It appears that I may have enabled this plugin when I rebuilt my apache using EasyApache. Are there any big benefits to this? Looking at the graphics at first glance it doesn't look like there is. but then again, I'm not that knowledgable about this stuff.
I have Munin running on my Centos 5.2 box, but would like the 95th percentile calculations. I have found this page for an add on:
[url]
where to put this code and/or how to install it?
Does anyone have a tutorial or instructions to show how to set up munin to monitor bandwidth/traffic utilization?
I have a VPS from a provider that has no monitoring tools, and I need something to monitor.
(The VPS uses the HyperVM software.)
I am using the CentOS version 4.x right now, and munin is already set up and configured with a basic install.
Anyone know how to add traffic/bandwidth monitoring? (Ideally, it would monitor all active ports.. but I only really need it to monitor port 1194 for openVPN software.)
I rebooted my server and now munin is not showing any eth0 traffic. All other graphs are fine. I can see there is a ton of apache accesses so there is definitely eth0 traffic. Munin logs report no errors. I restarted munin and munin-node. I even did 'yum remove munin munin-node' and reinstalled again but it still doesn't work for eth0.
View 4 Replies View RelatedThe memory usage on my server has slowly been creeping up over the last few weeks due to increased load. Here is my munin memory usage graph for the last week:
[url]
Could someone tell me what I need to be looking for or how to interpret this?
The cache and buffers have been getting really high but also has the inactive memory… so its looks as though its using memory and marking it as inactive afterwards and although graph shows I have massive memory use at first glace it also shows I have half my ram inactive and therefore available to be used.
On Cpanel/WHM. I have just moved from a VPS to a dedicated server. I reinstalled munin, so get some stats via that. I used to have apachetop loaded on my VPS for when I wanted a 'near realtime' streaming view of apache access.
I'm wondering what the best solution is to get a good view of apache, like what apachetop did, plus also it would be nice to have a real-time monitor of MySQL activity, HDD activity (such as I/O queues, etc. Something along the lines of the perfmon on Windows servers.
What is my best option?
Also, with Nagios, when I look at the website, it seems there are two options. Load it on a single server and then load the stats via [url]or have the Nagios 'stat collector' on one machine, and have it gathering stats from multiple machines.
If you only install it on a single dedicated server, do you really have to be on the console and connect to the Nagios stats via localhost, rather than connecting remotely?
Ideally, I would like a quick, easy to setup solution, but if it takes some configuring, I can deal with it, as long as there is some documentation. My main goal is to get the real time type monitoring, you get with window's perfmon.
I'm setting up a PHP shop website and the script that I'm going to be using has a pretty heavy list of requirements.
Instead of looking for hosting software packages, I was wondering that are there any hosts that offer an "empty box" where clients can install all the needed software (apache, php, mysql, etc...)?
If not, then what would be the best host for getting a custom PHP build (I'm looking for PHP 5.20).
I am trying to delete none empty directory using this command...
rmdir dirname
but system say directory not empty.. how I can delete directory with all directory/files under it
I'm having some problems with my script, i think its not really a script error...
- Script connects to rapidshare to send a file to the user
- Rapidshare allows unlimited parallel connections, so no problem
- Though some of the time (not alot), i get a connection error.
- Connection error is: Empty reply from server
- Strange thing is, i get this when i do a curl connection to rapidshare
- ping, telnet, fsockopen, all is working, but it seems that i don't get a reply from the server
Well, is this a problem on my side or on the rapidshare servers?
Also, is there a problem to fix this?
Server is using:
- curl 7.15.5
- php 5.21
- apache 2.2.3
there's no firewall setup on my site..., also i can't find anything in iptables,...
/etc/init.d/iptables status
Table: mangle
Table: filter
Table: nat
/sbin/iptables -v -I INPUT -s 1.1.1.1 -j DROP
no "response"
.. this means the iptables are simply empty I guess!
CSF is enabled and working, at least it's sending me mails that it's blocking IP's or if CPU load is too high.
/etc/init.d/iptables status is working but not saving anything

I currently have my own dedicated server located with the following prefs;
Linux: CentOS 4.6 (final)
Kernel Version: 2.6.9-67.0.15.ELsmp
I know this is possible, but I am seeking how to drop empty udp packets automatically with iptables.
Some bot(s) without a reported IP address seems to be making 60 - 500 connections to my server constantly even though there are usually only a few real users connected.
Does some search engines/some legit proxy users have no reported/hidden IP address?
Am I even able to ban an empty IP with iptables?
Today i checked my server and when i click in Install a RPM it shows epmty list!
I tried to rebuild rpm databse it rebuilded it without any error but still empty?
any idea?
Also when i click on Apache Build/Upgrade Is ee this
