Cacti

Hi BSOD2600, sorry, you are wrong. This isn't a SNMP 32/64 bit thing of the interface counters. I run into this pretty long ago with gigabit Ethernet :-) I'm using the 64 bit counters already and the graphs correctly display significantly more than a few 100mbit/s... The problem is that the bandwith...

Hello everyone, I'm puzzled by my new routers and Cacti. It seems that for all interfaces (physical & port channels) starting with 10G my routers report 4294967295 as the ifSpeed. Although this is "a lot", it is not quite enough because the data sources are limited to this value :-(. T...

Hi, I intended to roll forward my boosted cacti (up to now 0.87e with patches for spine and boost 4) in the direction of 0.8.7g. I started out with updating spine to 0.8.7gB2 and didn't touch cacti because it's a bit complicated due to the number of plugins involved. First impression was "WOW&q...

Hi TheWitness the 2.5-1 Version of Boost just rocks! The "Enable direct population of poller_output_boost" reduced my polling time from >80seconds to just 40seconds. Guess the "25%" time reduction is a little bit on the safe side of things? This is so great work, I'm totally out ...

Hi, sorry for coming back with this thing after so long time: I played around with the variables but I don't see much change. mysql insert size: tried 500k, 1000k, 2000k run time varied 1-2 seconds. Am I right that the maximum records maximum data sources per pass maximum argument length are just fo...

Hi Witness, Hm. I changed the poller_output table so that "output" isn't a text anymore but a varchar field (hope that 128 is long enough...) and committed the table to memory. poller_output | CREATE TABLE `poller_output` ( `local_data_id` mediumint(8) unsigned NOT NULL default '0', `rrd_n...

Hello Witness, first of all thanks for trying to help. mysql> ALTER TABLE poller_output, ENGINE=MEMORY; ERROR 1163 (42000): The used table type doesn't support BLOB/TEXT columns The other one did work ok, but with little immediate effect. Generally the behaviour didn't change, I'll keep it running t...

Hello and thanks for picking this thing up... The questionable output is (I figure the blurp around isn't really needed): | poller_output_boost | CREATE TABLE `poller_output_boost` ( `local_data_id` mediumint(8) unsigned NOT NULL default '0', `rrd_name` varchar(19) NOT NULL default '', `time` dateti...

Hi, I'm confused with the cacti/spine/boost poller behaviour. Poller behaviour looks like this: when the poller starts via cron it "immediately" hits heavily on the network for about 20 to 30 seconds like one would expect :-) During this time I also see 100-300% of mysql cpu activity in to...

Hi, I'm currently monitoring about 20000 network interfaces with a cacti/boost setup. The switches / ports are automagically imported with CLI. Works like a charm. Anyway it would be great if it were possible to set thresholds for all the error graphs so that if a value of e.g. 0.1 error / s is exce...

Hi, it took me several hours of nasty debugging (newbie to boost, no PHP god) until I realized that boost isn't fully compatible with the "Structured RRA Path" option from 0.8.7c. That means that boost simply isn't able to create new graphs when the subdirectory the graph shall go into (.....

Hi all, running cacti on a low memory server I stumbled upon a very ghastly error condition. When the system was short on memory apache looped when I tried to open a rrd and threw tons of "fgets(): supplied argument is not a valid stream resource" into the httpd error log file. It took me ...

Hi, I stumbled upon an "off by one" error in the is_ipaddress function in ping.php from cacti 0.8.7b. For IPv4 adresses there is a loop: foreach($octets as $octet) { if(($octet < 0) || ($octet >= 255)) { return false; } } Unfortunately there are valid IPv4 addresses around that contain a 2...
