While using PRTG to monitor our firewalls, we found by default it could not poll Juniper SRX’s CPU and flow information with auto discovery method. From command line, we are able to use following SNMP Mib to get CPU, Memory and Flow Session information, but not directly from PRTG.
PRTG is powerful network monitoring tools for enterprise with following features I likes :
- Easy to deployment, as it said it can be installed in 2 minutes
- Auto discovery methods to find monitoring elements.
- Support distribution implementation. You could install agents it in multiple location.
- Support Multiple protocols, such as SNMP, WMI, Netflow, jflow and sFlow etc.
- Web Interface is quite intuitionistic
- Email function
- etc

2. Add sensors into PRTG
Since we already have MIB information in the SRX, here is the manual way to add those information into PRTG.
3. SRX1400 Mib Information
For SRX1400, SPU is in the different slot, you will just need to change slot number from 0 to 1.

4. CPU for Routing Engine
SRX branch also have a SPU (Service Processing Unit). Considering SRX branch doesn’t have a dedicated SPU chip, but due to it’s muticore infrasture, it will use one logical core act as RE, and other logical core act as SPU, this SPU always sit in FPC0.
The following MIB is for Routing Engine CPU Poll.
