Robert, Do you know what revision you were running when it still worked? Probably something broke or disappeared or so when you updated a few weeks ago and didnt get fixed until now... Tom ----- Reply message ----- From: "Robert Williams" <Robert(a)CustodianDC.com> To: "'Observium Network Observation System'" <observium(a)observium.org> Subject: [Observium] C6K Fabric stats not being recorded any more Date: Fri, Feb 3, 2012 10:55 Hi all, I'm still not getting very far with this one :( Out of desperation I deleted and re-added one 6509 chassis and now it doesn't even show the stats for the fabric, it's just missing the whole "Catalyst 6k Crossbar" section? I'm running the latest (2854) revision. Any ideas please?

Data is visible up to a couple of weeks ago, but then stops and nothing more has been recorded since. The permission on the rrd are fine, and the file itself hasn't been modified since the day the data stopped being recorded. Interestingly, the usage 'bar' next to the (blank) graph shows usage on it correctly. So, as a test, I moved the rrd files for one chassis out of its folder then did a full redetect of the one host in question. Since then it doesn't appear to have made any effort to re-create the RRD file :( So, any ideas on why this one element would stop working suddenly? Or alternatively, is there a way to 'force' Observium to re-create it's rrd files for specific sensors on demand? Any input most welcome :) Cheers, _______________________________________________ observium mailing list observium(a)observium.org http://postman.memetic.org/cgi-bin/mailman/listinfo/observium

Feature Request/Suggestion: Trending
by Ciro Iriarte 24 Jan '12

24 Jan '12

Hi, it would be really helpful for Capacity Planning to include Trending support, as far as I know, RRDTool already has support for it. Maybe adding trending on all graphs is not the best option, because for one graph there are many data sources, and while one can choose what one thinks would be the most obvious candidate another user might need to do the trending using other datasource... Maybe adding a separate TAB where one can choose what to graph with trending would be the most "universal" solution, or maybe a mix of both, graph the obvious by default and enable and "advanced" tab for trending on demand...

Collectd alongside Observium
by Ciro Iriarte 24 Jan '12

24 Jan '12

Hi, I'll try asking again splitting topics... Does collectd add new data/features not available with SNMP polling?, should I implement collectd alongside a new Observium installation?. Also, which version plays nice with Observium today?, 4.10 or 5.0? Regards, -- Ciro Iriarte http://cyruspy.wordpress.com --

Load Graph, 'm'illions?
by Ciro Iriarte 24 Jan '12

24 Jan '12

Sorry if this has been asked before, couldn't find the answer in a quick search. Graphing Linux load average on a busy machine I see integer numbers, which is expected "20" for example, but graphing an almost idle machine (load 0.22), it's graphed as 220 m. Is there something I need to adjust?, is a RRD limitation? Regards, -- Ciro Iriarte http://cyruspy.wordpress.com --

"Could not ping <host>" from Web UI
by Ciro Iriarte 24 Jan '12

24 Jan '12

Hi, I managed to install Observium rev2831 on SLES11SP1, and it's working great!! Trying to add hosts by CLI I was getting the "cannot ping" message, fixed it adding "$config['fping'] = "/usr/sbin/fping";" to config.php. Now, I keep getting the same trying to use the Web UI to add a hosts, apparently it's not using the config['fping'] variable. Is that possible? Regards, -- Ciro Iriarte http://cyruspy.wordpress.com --
