Re: [collectd] Collectd, snmp linux interface stats
Hi Bill, I don't feel that is the case for me sadly. If I run the following : snmpwalk -v2c -c public switch IF-MIB::ifDescr --SNIP-- IF-MIB::ifDescr.53 = STRING: VLAN10 IF-MIB::ifDescr.54 = STRING: VLAN50 IF-MIB::ifDescr.55 = STRING: VLAN90 --SNIP-- I can see my three VLAN's. If i attempt to query them (in/out stats) I get an error : snmpwalk -v2c -c public@10 rackswitch IF-MIB::ifOutOctets.53 IF-MIB::ifOutOctets.53 = No Such Instance currently exists at this OID With or with out the @VLANID, makes no difference. Maybe this is a Cisco IOS issue? As my Cisco router works fine with the above examples.

Hi, If I were you I'd use one of the latest collectd builds, which has a fix [1] which seems to address issues ppl are having especially on Cisco hw.

Re: [collectd] processes plugin process by name - percent of all cpus feature
Hello, Excerpts from William Salt's message of 2013-06-17 02:00:35 +0200: Im using the processes plugin to find specific processes via regex, and monitoring their cpu usage, this is the total time spent in jiffies (milliseconds) across all cores. In graphite, i am dividing it by the number of cpu cores i have on a machine then turning that into percent. this gives me a percentage of total cpu usage across all cores for that process. However, i cannot ascertain in graphite the exact number of cpus a node has, it differs greatly, and its not scalable to have static values in graph query strings like this, nor efficient to work this out when rendering a graph. Still not very nice and efficient, but you can use a variant of this[1] to count the number of cpus using graphite functions. IE: this would return the number of CPUs as seen by collectd's spu plugin: sumSeries(offset(scale(collectd.your_hostname.cpu-*.cpu-idle, 0), 1)) Another thing that comes to mind: since collectd 5.3 there's an aggregation plugin, which you can use to sum up the metrics of every cpu on each host. You could then use these aggregated metrics for your percentage calculation. There's a similar feature in graphite if you run the carbon-aggregator in front of carbon-cache. I wondered if someone could patch the plugin to allow a flag to produce the average cpu use across all cores? grabbing the number of cpus from /proc/cpuinfo and dividing the metric by that? bonus if it had a flag to output a percent! Vedran Bartonicek has 2 pull-requests doing this sort of thing for the load and df plugins.

Good day! In collected metrics I hadn't found two very interesting for me. I don't found metric disk queue length for disk plugin and media connected or so on for netlink or interface plugin I think it will be helpful Thanks forward!
