ACI - Callhome config - Empty email received

[ju.mahieu]

Hi,

APIC running version : 2.1(1h)

I have followed the LAB described below

https://supportforums.cisco.com/sites/default/files/lab1g-externaldatacollectors-callhome-m1-tdeleon.pdf

My configuration seems to be correct but unfortunately I'm receiving email from the Apic with an empty body and a blank subject. 

(Format short-txt and xml)

Did you already have this kind of issue ?

How can I check easily the callhome config and see the statistics ? 

Is there any way on the Apic to capture Smtp traffic on the oobmgmt ?

Thank you (Again ;-).

Ju

Hi Ju,

The minimum configuration needed to test CallHome is:
CallHome Desintation Group with CallHome Destination
CallHome Source defined under either Fabric or Access Policies
Configuring Scheduler is only required when configuring CallHome Inventory

CallHome messages are sent mostly from APIC2 when the APIC cluster size is 3; we can verify if CallHome is sending emails by running tcpdump on the appropriate interface of the devices.
After reviewing the tcpdump outputs, we can confirm whether or not the device is sending out the CallHome emails.

If we see traffic being sent by the interface, we can also review the svc_ifc_eventmgr.bin.log.stderr file for the output of the sessions with the SMTP server.

CallHome logs are located in the device that is sending the CallHome emails under the svc_ifc_eventmgr.bin.log file.

Log Locations (assuming APIC2 is sending the CallHome emails):
In the log file of the TechSupport for APIC2, the log can be found under /data/log/.
In a live environment, the log can be found in APIC2 under /var/log/dme/log/.

Hi Manish,

You will find attached my detailed config.

Could you check if something is wrong or missing, explaining why I'm receiving empty email from the apic ?

About the tcpdump, I don't have enough privilege to launch the command.

Best regards

Ju

Ju,

What versions are you running on your APIC & Leaf\Spine nodes?

I used your setup in my lab and it works as expected.

The fact that you are receiving an email from the APIC indicates the configuration is configured correct or at least partially.

Can you send me the text output of the long message display of the email message?

Also, try removing the monitoring policies for Callhome under "Fabric Policies - DEFAULT" and "Access Policies - DEFAULT".  Then, configure  "Fabric Policies - COMMON" only for callhome and your callhome destination group.

and retest.

Thanks

T.

Hi Thomas,

I'm running  2.1(1h) and n9000-12.1(1h)

You are right. The header coming from the long message display is correct :

Probably a security parameter in my outlook client.

Thank you for your help.
