PRTG
PRTG is by far my favoured tool for monitoring IT infrastructure. With its built in sensors you can check the PING time for a server, check that windows services are up and running or with a little tweaking monitor paper trays in a MFP (and so much more).
A recently discovered feature for me is the sFlow monitor. This tracks in near real time the flow of different types of data (e.g. SMTP/HTTP/FTP/DNS lookups) that flow through network infrastructure.
In my case the entire network is built on HP ProCurve layer 2/3 switches which makes for pretty easy setup.
To follow this guide you will need
- The IP address of your PRTG server (in my case 172.16.8.27)
- Admin access to your PRTG console and a ‘device’ setup for your switch
- Admin access to your switches through Telnet/SSH (I use PuTTY to administer my switches through Telnet)
- 5 minutes
So now that I have all of this extra info what am I to do with it? Well with the sFlow sensor setup you can…
- See if your network infrastructure is experiencing bottlenecks…
- …and if so where the bottleneck is and what kind of data is causing it (e.g. large file transfers)…
- …and see what clients are causing it.
There are lots of great reasons to replace personal printers with centralised photocopiers but one of the overlooked ones can be the greater ability to monitor these copiers using SNMP (Simple Network Management Protocol).
This article looks at keeping track of the status of the paper trays (how full they are!) using PRTG (http://www.paessler.com/prtg) on Sharp photocopiers.
To get rolling you will need-
- PRTG (or some other item of software that can talk to SNMP)
- Some way of querying the SNMP OIDs on the copiers (for this article I used the free version of MIB Browser – http://ireasoning.com/mibbrowser.shtml)
- A little bit of ingenuity
If just by chance you are using the Sharp MX-2640N copiers then you can save time by using the following OIDs-
Paper Tray 1 Status .1.3.6.1.2.1.43.8.2.1.10.1.2
Paper Tray 2 Status .1.3.6.1.2.1.43.8.2.1.10.1.3
Paper Tray 3 Status .1.3.6.1.2.1.43.8.2.1.10.1.4
Paper Tray 4 (A3) Status .1.3.6.1.2.1.43.8.2.1.10.1.5
So to get this up and running follow the screen shot sequence below.
