Hi all, My first post here. First I must say that Observium is the most easy looking open source tool I have ever seen :)
I'm trying to figure out a few config items that maybe someone can help me with.
Autodiscovery If I'm using $config['autodiscovery']['xdp'] = TRUE; and $config['autodiscovery']['snmpscan'] = TRUE; First it does not seems to add any devices discovered with LLDP/CDP, nor have I found a way to do a snmpscan based on my subnets (also added)
1.) Does Autodiscover work as the config file says the feature is not yet added?
PTR/DNS Does observium require a PTR record for every device or just a valid host name trough SNMP? How about FQDN?
WMI Seems to be a topic not much covered and not really supported, however in the modules section of a device, let's say a server one can find an on/off switch for WMI and also a settings page. Does this mean WMI is somewhat supported or just a GUI glitch?
Thanks
for CDP/LLDP autodiscovery to work you need this: 1) device address is inside the subnet(s) added in $config['autodiscovery']['ip_nets'] 2) device configured hostname match DNS hostname 3) device domain-name match DNS domain
for exampel if you have a cisco switch with dns address: switch1.mgmt.company.com you need to have this config in the swtich: hostname switch1 ip domain-name mgmt.company.com
Observium will get hostname and domain name via CDP/LLDP and then try to resolve it.
For OSPF/BGP autodiscovery you will also need PTR to match as observium will find a OSPF peer with address 192.168.58.1 and then looks for PTR for that address before it can be added.

FQDN's (or at least resolvable by /etc/hosts) is required.

Hi....
Just a silly question. I was googling around for number but could not find meaningful reallife data.
I am running now an observium instance for about a year. I am polling presently 22 serves, 14 switches and 1 printer. Alltogether 1004 ports. My mysql database is now 189 GB big. I need to resize my filesystem soon.
Attached you can also find my statistics output from observium
Is this database size normal? How big can it grow? in one year? In 2 years? Is there an upper ceiling? What are your database sizes (maybe in a similar scenario)?
Thanks for your help,
Roland
Hi,
Try running the housekeeping script to remove old data.
./housekeeping.php -a -A 6M
This will cleanup old syslog entries, events, alert logs, deleted ports, timing data and old RRD files (-a) all information older than 6 Months.
Run it as ./housekeeping.php -h to see all the options.
Regards
Bruce

It's a lot.
We a lot more devices on our setup. Running since September and here are our stats :

Looks like someone added DB and RRD size to the About page for us. Here's ours:
[cid:image001.png@01D0818C.8A232CF0]
We have 5 servers, 48 network, 1 wireless, 1 firewall, 34 power, 1 voip, and 1 storage devices. -- Cameron Moore

you are great!
here an open caveat I have about db and rrd size (and that may hit others too): we have many ppp connections which create each time a new (virtual) interface on the routers: observium each time discover new interfacese, create rrds (and db records) and THEN delete them from the db (as they are marked as "bad_iftype" and/or "bad_if_regexp").
of course I have a scheduled housekeeping.php to delete all these rrds, but it's a waste of i/o to create thousands unused of rrds.
any hints?
