All this is doable, as you already found out. But it's not optimal, performance wise. Answer to your first question: spine will poll/execute the scripts/script server scripts itself. But as those scripts are php code, they are way slower than anything fetched via SNMP. AKA: spine will spawn a PHP p...

How many nodes is not that important. The number of datasources is. Also, the required polling interval it's a very important factor. I monitor about 900 devices, 26.000 DS, 21.000 graphs with a dual processor Xeon 5060 (dual-core with HT) & 3GB ram. The RAM usage is about 1-1.5GB (MySQL include...

AFAIK rrdtool minimum granularity is 1 minute.

Errr... bump :) I have a script that pings my devices. If they don't respond to SNMP, i don't want most of the graphs created, but I DO want the ping graphs to be made. That's because the device can respond to ping but not to SNMP. I will probably implement a dirty little hack, but it would be nice ...

Hello! My setup: 2 x Xeon 5060 (Dual-core 3.2GHz with Hyper-threading) 943 devices 40372 data sources 18644 graphs Poller item stats: 38750 SNMP, 21 scripts, 1601 script server Polling time average: 17 seconds. Cacti 0.8.7g, spine & boost 4.0 The best polling performance that I get it's with 6 p...

1st patch: possible, but now it works OK. Without that, i was getting a lot of poller timeouts.

2nd patch: yes, of course I've tried. My SNMP timeout is set to 500ms and I've tried increasing it up to 3 seconds. I still got about the same amount of 'random' timeouts.

Patch #1 Sometimes, spine caused a segmentation fault. Tested with 0.8.7g and the SVN version. With GDB, i got to the following line: poller.c, function poll_device: --- /z/spine/branches/main/poller.c 2011-03-24 11:53:58.000000000 +0200 +++ poller.c 2011-03-25 01:09:41.000000000 +0200 @@ -1052,7 +1...

Uhhmm... no, sorry. I didn't knew that patches are already out for 0.8.7g. I'll apply them and post if I have troubles anymore.

I have a problem with graph filtering (only by name searching, host and template works) into List Mode: I input the search string, press on 'Go', page is reloaded, but Search box is empty and no filter is applied. Filtering in Tree & Preview mode works ok. Anyone else has the same problem, or sh...

Excuse me, my mistake.
Plugin was not enabled in the 'Plugin Management' Section

I tought that if i see 'Boost' tab in Settings everyting is ok.

I've installed upgraded to Cacti 0.8.7g final (only DB kept from an older version) and installed Boost plugin from SVN (4.2). No other plugin installed. Boost it's not working. poller_output_boost table (MEMORY) gets to 512MB and that's it. But the RRD files are updated every polling cycle: 07/29/20...

I've played a little with the ss_valute.php script and, at some moment, it returned erroneus values. That's OK. BUT the graphs that were using ss_dobanzi.php (another script, another table, etc) went crazy too! ------------------------- Okie, that made me look at the scripts from another server (mad...

1) Yep... I also made some scripts that work absolutely fine, on another server. 2) Sorry :D <?php /* do NOT run this script through a web browser */ if (!isset($_SERVER["argv"][0]) || isset($_SERVER['REQUEST_METHOD']) || isset($_SERVER['REMOTE_ADDR'])) { die("<br><strong>This script ...

Sorry . I didn't saw the last post date
