Newbie ?s - map config

Hello all, We’ve recently decided to move from Cacti, and tried Zenoss, and we’re now trying Observium. We’re *really* liking it. Device import went really well, and have been able to tune it to exactly what we need. I’m having issues with the map. The mapping of alerts is a pretty important feature for us, but I can’t seem to get it dialed in. You may certainly assume I know nothing about this mapping feature beyond the “Map Overview Settings” porton of the Configuration Options page. We’re a small campus so the scale of the map is not working out when we use the “US-565”. When the dots render they stack up. Is there a more ‘zoomed in’ option? How does one appropriately choose the ‘location’ data? If I can hop on google maps and put in a string and have it put a pin in the right building, is that string acceptable to use for the location field? I.E. “north hall library” gives me the correct location in google maps, does that mean I can use it for the location string? Since google maps has our building footprints drawn out, I’d prefer to use that layout, is it possible to switch it to that instead of the metro area shtick? Our map looks like this: [cid:image002.png@01CEA3E3.1FE973E0] Using the following in config.php //MAP data $config['frontpage']['map']['region'] = "US-565"; // See https://developers.google.com/chart/interactive/docs/gallery/geo$ $config['frontpage']['map']['resolution'] = "metros"; // Some region types such as US States (US-NY) require this to be changed t$ $config['frontpage']['map']['dotsize'] = 5; // Set the dotsize you want $config['frontpage']['map']['realworld'] = false; // Enable/Disable the realworld view (blue/green), if disabled default m$ Thanks! -Loren McNett

active/standby pairs (esp. FW)
by Rob VanHooren 28 Aug '13

28 Aug '13

some gear that's put up in pairs insists on having the same hostname/sysName, e.g. ASAs. even though their m0 are uniquely reachable, there's no currently obvious way to watch the standby, since even though its DNS is unique, addhost sees sysName and rejects it as being a duplicate. ideas? tks, R.

Incomplete device name (bug?)
by Richard Hartensveld 28 Aug '13

28 Aug '13

Hi all, If I add a device with a hostname of br0.abcdefg , it will show up nicely on the front page, however, when I add a device with a hostname of br0.abcdefgh (or longer), the device's name will be 'br0' on the front page under "device alerts" and "Recent Eventlog Entries". If you hoover over the device name, he popup screen wil display the correct device name. Could this be a bug, or am I doing something wrong ? Thanks. gr, Richard

Mis-aligned data in memcached app
by Sander Steffann 28 Aug '13

Hi, When debugging why my memcached graphs weren't working I discovered the following problem: SQL[SELECT * FROM `applications` WHERE `device_id` = '41' AND `app_type` = 'memcached'] Including: applications/memcached.inc.phpmemcachedmemcached(127.0.0.1:11211) SQL[SELECT app_id FROM `applications` WHERE `device_id` = '41' AND `app_instance` = '127.0.0.1:11211'] RRD[cmd[update /opt/observium/rrd/v25.invalpool.nl/app-memcached-127.0.0.1_11211.rrd N:64:2.0.16-stable:0:0:5:1045:6202:8:0:0:14045:129043:6202:0:0:0:0:7184655:13093279] stdout[ERROR: /opt/observium/rrd/v25.invalpool.nl/app-memcached-127.0.0.1_11211.rrd: conversion of '2.0.16-stable' to float not complete: tail '.16-stable'] stderr[]] Obviously the data in the rrdtool update command were wrong. A version number shouldn't be in there... So I looked at what the memcached agent script was returning and how that was parsed by the poller memcached module. It turns out that there is a difference. The agent script returns a list of values in this order: accepting_conns, auth_cmds, auth_errors, bytes, bytes_read, bytes_written, cas_badval, cas_hits, cas_misses, cmd_flush, cmd_get, cmd_set, cmd_touch, conn_yields, connection_structures, curr_connections, curr_items, decr_hits, decr_misses, delete_hits, delete_misses, evicted_unfetched, evictions, expired_unfetched, get_hits, get_misses, hash_bytes, hash_is_expanding, hash_power_level, incr_hits, incr_misses, libevent, limit_maxbytes, listen_disabled_num, pid, pointer_size, reclaimed, reserved_fds, rusage_system, rusage_user, threads, time, total_connections, total_items, touch_hits, touch_misses, uptime, version The poller module parses them in this order: accepting_conns, auth_cmds, auth_errors, bytes, bytes_read, bytes_written, cas_badval, cas_hits, cas_misses, cmd_flush, cmd_get, cmd_set, conn_yields, connection_structures, curr_connections, curr_items, decr_hits, decr_misses, delete_hits, delete_misses, evictions, get_hits, get_misses, incr_hits, incr_misses, limit_maxbytes, listen_disabled_num, pid, pointer_size, rusage_system, rusage_user, threads, time, total_connections, total_items, uptime, version As you can see this breaks at cmd_touch: the agent sends a variable the poller doesn't expect, and as the data is sent value-only it has no way to determine that the imput is in different places than it expects... What I suggest to do is the following: - update the agent so that key:value is sent instead of just value - update the poller module so that it can parse key:value input - make the poller module also accept the current value-only input as a fall-back If we agree that this is the way forward I'll send in a patch. Cheers, Sander

Location debug : how ?
by Xavier Beaudouin 27 Aug '13

27 Aug '13

Hello, For some reason, on my observium at work, seems that location doesn't want to work. On device menun, still marked as "unkown". I tried to find is there is an issue with the location part, but on a setup at home, it is working. Location like Paris, FR / Belfort, FR still fail into unknown, so I wish to debug what happened, and how to fix it (maybe this an issue with my setup, but I cannot find where). Any hints about that?

Horizontal Scalability

Hi!, anybody considered scaling adding more servers instead of going to a bigger one?. Using something like Open Grid Scheduler for example. Currently I'm maxing out our server (2 x Xeon E5-2630, 16 cores) with 37500 ports, 548 devices cplanning:~ # uptime 13:19pm up 151 days 3:03, 2 users, load average: 43.37, 43.00, 42.60 Regards, CI.-
