OIDs for Fortigtate firewalls

Fortinet firewalls can be monitored using any SNMP capable device. You can look into CPU usage, memory usage, number of sessions, utilization on interfaces and so forth.

But it is not always easy to know how to do this. I needed to monitor CPU, memory and # of sessions on a firewall. Here are the OIDs to do so. Tested on FortiOS 3.0

CPU load	1.3.6.1.4.1.12356.1.8.0
Memory usage	1.3.6.1.4.1.12356.1.9.0
Number of current sessions	1.3.6.1.4.1.12356.1.10.0

These values can be added directly to SNMP tools such as PRTG and MRTG.

PRTG traffic grapher

Have you ever needed to make graphs out of your interfaces in one way or another. I guess you are familiar with MRTG, a Unix tool written in Perl that polls all your SNMP devices and makes good looking charts out of them.

If you are a Windows user and do not know how to configure Apache and MRTG then I have the solution for you.

PRTG - a tool from a German company is exactly this. A replacement for MRTG, running on Windows and with it's own web server.

PRTG is not free of charge as MRTG. But the cost is relatively low and it is good value.

From a Windows application you can configure everything you need to monitor and later on just watch everything from a web browser.

Pegasys TMPGEnc

This tool encodes your input stream into any MPEG supported output, including DVDs. It is not a tool to edit your videos, just to encode them.

bind9 multiple RRs of singleon type

On an issue I have been working on a zone did not load on the bind9 server. When debugging I ran across the message "multiple RRs of singleon type". To find this error message I had to run named as "named -g -u bind -d 9". According to an article I found on this matter it is related to duplicate CNAMEs or SOA records on a zone.

I started out by looking into the zone file (sort zone.db) and quickly found two almost identical SOA records.

I deleted one line and after a quick reload of named everything started working.
