similar to: Outbound traffic spike every 30 minutes

Is inbound or outbound?

Since Sunday morning, one of my CentOS servers has been generating a small spike of outbound traffic every 30 minutes (X:00 and X:30). It's not enough traffic to really cause any notice except for the fact that it is a very regular pattern and it started abruptly at midnight Sunday. This server is used for mail (Courier-MTA), and DNS (Bind). I cannot find anything unusual in either of

Hi, I've been getting regular CPU usage spikes(50%-80%), due to asterisk (according to top). I never noticed this on 1.4, and I have top running in the background pretty much all the time. In between those spikes Asterisk stays under 10% CPU usage (I have a transcoder card, which helps). It's very regular, never any missed spike, or any spike in between the regular spikes. I

You could use any of these hyperic, cricket depending on your needs and wants... I use/used cacti, ganglia, mrtg and hyperic... ganglia we currently use to gather performance data and replaced hyperic (better fit for us) and we also use

I finally got (mostly) what I wanted. In an attempt to figure out how to get nls to deal with a non-differentiable function, I had (stupidly) 'simplified' the problem until it became singular. Can I do something to make optim() less sensitive to my initial guess? For this example, I get a lousy solution if I make the initial guess for t0 = min(t) = 0.05. Thanks again, -- Robert Merithew

Hi all, I've uploaded STAR (Spike Train Analysis with R) on CRAN two days ago. The package is designed to analyze neuronal spike (action potential) trains. It uses S3 classes and methods and makes heavy use of other CRAN packages like gss, R2HTML, mgcv, survival. * Analysis of both spontaneous and stimulus evoked activity is implemented for single neuron spike trains as well as for many

Hi, I'm working with custom slides(Cy5) and working in the normalization of the arrays. I have three arrays (technical replicates). I have sucesfully normalized the data using vsn, however i would like to normalize using spike in controls. My controls are annotated as CTL-1 to x and i would like to do etiher a normalization by block per array or the mean of all the controls per array. The gal

I am running Asterisk V 1.4.22 Twice during the last two days the Context Switches on our box has gone from about 7K to 80K in 2.5 hours. The load average would spike to 17, drop to 0.35 then spike again. When connecting to the console 'core show channels' will list the channels but not total calls. 'restart now' had no effect, the only way to stop Asterisk is to kill the

Hi.. I am setting up a new server (2GHz CPU, Ubuntu 8.10) and am using dovecot for an IMAP server. I have installed dovecot 1.1.4 and Squirrelmail 1.4.15. sudo dovecot -n shows this: # 1.1.4: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_process_per_connection: no

I just encountered a weird issue on my servers - Tinc was using a constant 10-50% CPU on several servers, and these servers were also receiving a constant ~3 Mb/s of data over the Tinc interface, which is usually otherwise pretty quiet.

hello list, I'm trying to install ganglia-gmetad on centos 5.6. rrdtool is already installed and librrd is there. But for some reason when I go to install this package it doesn't see that it is. [root at VIRTCENT11:/usr/local/src/ganglia-3.2.0] #yum install ganglia-gmetad Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile * base: mirrors.lga7.us.voxel.net

BTW, there seems to be an issue with the yp servers traffic handling. After motherfish came back up today (from 3 days of downtime) mysql drove the load average up to 200, with the maximum number of mysqld instances all spinning in some kind of active wait. I attached to several but strace showed no activity during the period I was watching. This is quite bad; we assumed something was wrong

We run ganglia on a 35 node cluster (plus a few odds and ends). It seems pretty lightweight. I've just finished installing the latest versions at home on old slow 32-bit kit and it seems again to be very lightweight. You will need to install libconfuse and RRD though, the former comes as a tarball. You'll need to configure/make/make install and then tell yum to ignore the missing

Hi everyone, I'm running dovecot with quite a lot of users and lots of active imap connections (like 20'000). I'm using different user IDs for users, so I need to have imap {service_count=1} - i.e. I have a lots of imap processes running. Everything works fine, until I reload dovecot configuration. When that happen, every client is forced to relogin in the same time and that

Dear All, I'm having a problem with my Asterisk + E100P Installation in UK (BT PRI). The system functions as expected, and my dial plan works as expected. 30 minutes (or so) after starting the asterisk service I lose the PRI line, and only get this back after a service asterisk restart or reboot. During the failure there is no alarm on zttool, ztcfg show all 31 lines and there are no

Hi, ? I've recently moved from OpenVPN to Tinc for the mesh setup. Everything works nicely except for some looping packet issues. ? I have 12 servers around the United States, including a couple of moving clients. Every now and then the network is flooded with what I assume is looping packets. 200-300MB of bandwidth per node over 10-45 minutes (normally < 20 KB/s, idle). Most if not all

Hello everyone, I know this isn't strictly CentOS query, but I am hoping that someone here with more experience than myself might have some thoughts. I am trying to get a plugin working for Ganglia on a CentOS 5.5 box, in a testing environment. The plugin is for apache monitoring, called Ganglia-Logtailer. This plugin requires the executable /usr/bin/logtail in order to work. The only
