Small-scale SNMP reporting

02/13/2008  
Relevance: 10.77
The Simple Network Management Protocol (SNMP) is a useful tool for examining the state of devices on a network. The open source world offers a number of consoles designed to manage the information from these devices and produce reports. However, there are circumstances in which access to the devices at a more customizable level is more beneficial. Given that the programming involved is minimal, it is worth considering custom applications for SNMP reporting.

Tips and tricks: What is a Command Center notification and how can I acknowledge a notification?

01/22/2008  
Relevance: 10.45
A notification is an email, page or SNMP trap that is generated when a host changes its state or when a service check has exceeded the configured thresholds. Notifications are sent via three modes of communication: e-mail, SNMP trap, and pager. These can be acknowledged via e-mail. Only e-mail and pager notifications require acknowledgement, as SNMP traps do not participate in the escalation process.

Custom Monitoring MySQL and SNMP with BixData

02/03/2007  
Relevance: 7.08
With BixData you can monitor your servers as well as VMware and Xen. BixData includes pre-built plugins for things like CPU, Memory, Disk, etc. but any good monitoring tool needs to be customizable. BixData includes the basic ability to run scripts and record their exit values, similar to Nagios Plugins. BixData 2.7 adds support for importing data in more complex formats. This allows you to monitor almost anything. I'll go through the steps showing you how to monitor MySQL locally where an agent is installed and then the steps to monitor a device remotely through SNMP. The advantage of BixData is that any data available through a BixAgent works with the standard tools such as the situation room, scoreboards, notifications and the reporting system. All data are stored in standard SQL tables and are easily accessible.

HowTo Collect Traffic Stats from Akamai using Perl

10/08/2008  
Relevance: 4.18
In order to graph the traffic from Akamai, I used to use MRTG calling a PERL/SOAP script which retrieved and combined the data from multiple cpcodes. This proved to be quite inefficient as each combination meant a separate SOAP call. I had thought about injecting the data into Zenoss, but the nature of that project dealt more with SNMP and simple commands and was not the ideal recipient of a multi-faceted SOAP retrieval mechanism. I finally got a chance to rewrite it this year as a perl script which connects to Akamai, acquires ALL the cpcodes for a particular login and, based on the cpcode name prefix, organizes the data by creating/updating RRD files and graphing them as PNG images (as well as creating MRTG-like HTML files).
