Re: [collectd] RRDTool slowdowns

Ok, thanks to Alex that confirmed it, rrdtool-1.4 with cairo and pango is slower. So I recompiled collectd 4.10.0 with rrdtool-1.2.30, and now it's zillion of times faster than with rrdtool-1.4 I had to specify required libgcrypt-devel during build otherwise I get a macro error in configure step

[collectd] RRDTool slowdowns

Hi folks, I recently upgraded rrdtool from version 1.2 to 1.4. Previous version was using libattr, while the new makes use of pango / fontconfig / cairo for rendering. I'm noticing tremendous slowdowns in generation of rrdgraphs. It's about 10~20 times slower than before. I'm currently using only

[collectd] kernel message SIGCHLD set to SIG_IGN

Hi Florian, after having patched the code in order to compile collectd-4.8.1 on an old RedHat 9.0 system, I finally succeded. However in the logs I see the following warning message: Jan 29 23:11:48 server kernel: application bug: collectd(7755) has SIGCHLD set to SIG_IGN but calls wait(). Jan

Re: [collectd] Strange SNMP collection glitches

Hi friends, I had problems with SNMP collection of if_octets-WAN of three different Zyxel SHDSL routers. I had recurrent peaks, which let me think it would have been a problem with overflow. Florian suggested to dump via CSV to get the real values. This is the dump of CSV in the around of one of

[collectd] Config changes

Hi all, This is rather long, sorry for this. A few things about config file: 1. I noticed that 'LoadPlugin vserver' directive is not present anymore in collectd.conf, though the plugin is compiled. No trace of removal in the changelog has been found. Is this correct? 2. Couchdb is missing 'L
