Observium
 

Hi guyz i need small favor, I am setting up an observium monitoring server for study purpose.I don't want to use snmp for data collection so I am using check_mk_agent I installed it on the linux host machine.I can see the version and stuff using telnet command.But how can I collect these info into observium as graphs. Observium wesite contains very less information for a guy like me. If sombody have a good idea about this very help full thanks :) . Hope I will get some help :)

Unless you manage the debt of a country, design self-containing nuclear power plants, perform brain surgery or code the Linux kernel for a living that doesn't constitute a "small favor" in my book. The reason for that is that you have decided to disregard the main feature that is supposed to make working with Observium easy and select the feature that is still under development. And "studying" Observium using more advanced features without getting acquainted with common usage first does not make much sense.


http://www.observium.org/wiki/Docume..._Configuration and http://www.observium.org/wiki/Unix_Agent point to several instructions, for example http://www.observium.org/wiki/Applic...L#Instructions, showing you what to drop where on which host to enable monitoring. If that doesn't work for you I suggest you get on the http://www.observium.org/wiki/Mailin...s#General_List as that's the quickest way to get an answer from Observium users.

LOL xD
 

I was trying to do some project. Actually kind of trapped now.I was also thinking same about this.Thought maybe someone can give me some tips.Maybe have to work it out alone :P . Avoiding snmp is not a big deal its not that kind of secure and fast. if you can suggest some monitoring tools such as nagios it will be very helpful..Anyway thanks for the replay. :)

SNMP v3 does have security concerns. But using that as an argument to justify your choice for plain text-based TCP? Doesn't make any sense to me...


Unless you can explain in detail what is feature or purpose-wise "wrong" with Nagios it doesn't make any sense to list Icinga, OpenNMS, Pandora, WebNMS, Zabbix, Zenoss or other [0|1|2|3] network monitoring software...

Well, if you want to ignore the well-established standards of monitoring things, then yes, you will have to do it alone.

The Observium site tells you it uses MySQL as a backend database server. If you want to use telnet, then get whatever information you want into a text file, then write a script to read it, and insert records into the database. Which is VERY pointless, since SNMP is the de-facto standard for network monitoring. SNMPv3 provides encrypted packet capabilities, which is MUCH more secure than telnet is. http://en.wikipedia.org/wiki/Simple_...ocol#Version_3
If you don't want to use SNMP, then it doesn't matter WHAT you use for monitoring, since it's going to be dependent on whatever scripts/programs you write. Again, using such a script to parse text data from a telnet session is pointless, since all you're doing is something not as flexible as SNMP, and not supported by anything.

Confused
 

Hi guyz thanx for lots of replays. I am not that sure about snmp security. Is it that much secure then why nagios providing there own agent nrpe for collecting data, and why sites like bijk.com asks us to install there own agents.. and i heard an alternative to snmp is collectd and is more secure. Two confused now can you provide some sites or something for better info thanks.

Do you understand what SNMP is, how it works, and what the various parts of monitoring systems do?

SNMP will let a remote agent query a system, and return data based on that query. Agents are typically used to monitor processes, and other items that CANNOT be monitored with SNMP. You don't HAVE to use Nagios agents to monitor a remote system, but you'll miss alot of important data.
Google can tell you all about collectd..start there.

Again, if you want a COMPLETE, robust, standards-compliant monitoring system, use SNMP with any of the previously-mentioned monitoring systems. If you want to write your own using telnet (as you mentioned), then feel free.
