EX 4300 with PRTG SMTP sensor

‎09-28-2018 10:03 AM

Looks like SMTP traffic stopped working with PRTG. Using Junos: 14.1X53-D40.8 on EX 4300 - any suggestions.

 

Is there any way to download MIBs for SMTP traffic for 4300?

The first question is if the EX4300 is operating as pure L2 or some L3?  If you are saying that all IP traffic outside of SMTP works, and just SMTP does not, then I doubt this is an EX4300 issue.  EX4300 looks at only MAC and IP fields, assuming no FF is configured, so it does not know the difference between SMTP (which is maybe UDP?) and any other application traffic.

 

I'd suggest you look further and elsewhere.

 

Good luck.

Do a mib walk and see the data is seen in the bpx; later check the reachability between server and the box. Do tcpdump to confirm if the packet is sent,

Re: EX 4300 with PRTG SMTP sensor

What do you mean by this?

Looks like SMTP traffic stopped working with PRTG. Using Junos: 14.1X53-D40.8 on EX 4300 - any suggestions.

SMTP is not passing the ex4300?

The PRTG server cannot use SMTP after connecting to the ex4300?

SNMP from PRTG to the ex4300 is not working?

The SMTP sensor probe on PRTG stopped working to some other device through the ex4300?

Is the connection of PRTG to the ex4300 new?

 

To troubleshoot we need to determine the full network path and protocol variables at play.

Well this is not new setup, the problem is prtg is working fine for a week maybe two and then all of our Juniper switches timeouts according to PRTG. While PRTG says switch down - ping down - I can ping the switch from other clients with no issue. I have to try ping it directly from PRTG and see if the host is the issue. But definitely, these alerts are not true, making PRTG being worthless. 

 

Of course when open cases with both each other blame with no actual output. Its not only about 4300, its about other 2200 3300 too.

 

I was planning to use Nagios to monitor Juniper and just abandon PRTG (Windows2012 installation) troubleshooting. 

 

I wonder fs you guys have any instructions on how to use Nagios to monitor Juniper switch. My plan is just monitored just one and see if these alerts are true. Does not have to be Nagios but another tool so I can try for a moment. Any thoughts?

Hello...you cannot add this sensor type to the Hosted Probe of a PRTG hosted by Paessler instance. If you want to use this sensor type, please add it to a remote probe device.

The Add Sensor dialog appears when you manually add a new sensor to a device. It only shows the setting fields that are required for creating the sensor. Therefore, you will not see all setting fields in this dialog. You can change (nearly) all settings in the sensor's Settings tab later.

anyway it's not even possible with PRTG:

 

You cannot add any flow related sensors to the cloud probe of a hosted instance, but you can on the remote probe you add to said instance.  The resource overhead is too much.

 

Besides, we don't even allow the sensor to be added in places it cannot be added.

I have decided to use something else than PRTG for testing - OPSVIEW with SNMP to see if I have similar issues. This should tell me where is the problem - PRTG or Juniper. 

Looks like opsview is harder for administrating and for a first time it really needs to spend some time figuring it out how this works.

 

I was able to use sflow with SNMP for now with tow hosts and this is enough for now, so let's wait for results.
