I have done some searches but couldn't find much useful info as to where the problem might lie.
I'm running RRDTool 1.3.5(upgraded in the past several of minutes from 1.3.4) 64-bit on CentOS 5.1, with cacti 0.8.7b, previously I was running RRDTool 1.2.23 on CentOS 4.4 with the same cacti version. I wanted to migrate to 1.3.x because of the I/O improvements dealing with NFS. I made the switch to the 1.3.x code base on 12/12(had to upgrade the OS as well as 1.3.x wouldn't build on the older OS). With RRDTool 1.2.x the server was sustaining 200Mbit/s 24/7 most of which was NFS traffic, with 1.3.x the server is sustaining about 4.25Mbit/s. As far as back end spindles go with 1.2.x on my big fancy storage array it was consuming consistently roughly 170 megabytes per second from the controllers(disk reads, mostly cache hits the controllers have combined 24GB of cache), after upgrading to 1.3.x, it went down to a small fraction of that. The server updates roughly 9600 data sources per minute in about 750 files(15% cpu on a 8-core system). A far cry from the rrdtool 1.0.46-based system I built several years ago which would of needed 10x the I/O capacity that this one uses. Everything seems to work great, except I'd like to get real fixed width fonts back if possible. Example of graph taken earlier last year with rrdtool 1.2.x: http://portal.aphroland.org/~aphro/rrdtool-1.2-graph.png Example of graph taken a couple minutes ago with rrdtool 1.3.5: http://portal.aphroland.org/~aphro/rrdtool-1.3-graph.png Specifically note how the legend lines up cleaner in the graph generated by 1.2. The one thing to note is I did have to override the build depends when compiling it as CentOS 5.1 still doesn't quite meet the requirements: cairo-devel >= 1.4.6 is needed by rrdtool-1.3.5-1.el5.x86_64 pango-devel >= 1.17 is needed by rrdtool-1.3.5-1.el5.x86_64 I have: pango-devel-1.14.9-3.el5.centos cairo-devel-1.2.4-2.el5 I'm not sure if that would impact this or not. I tried playing around a bunch with the font path and stuff(under 1.3.4, haven't tried 1.3.5) but wasn't able to get good results, no matter what I tried it seemed to pick the same font. I'm sure I was doing a bunch of stuff wrong, despite having been using rrdtool pretty extensively for the past 5 years or so there's still a lot that eludes me. I did notice some minor font change going from 1.3.4 to 1.3.5, looks related to the changelog about cacti's titles. thanks nate _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
