NSO service logging with ncs.service_log

[Maksim12]

Hello All,

I'm wondering if anyone was able to log directly to NSO service using Python API ncs.service_log  https://developer.cisco.com/docs/nso/api/#!ncs-service_log

It might be missing a bit of a description. I'm not clear if path is path to service or to service/log. As well as type variable is missing a description.

My code example: 

    servicelog = ncs.service_log.ServiceLog(node)

    servicelog.error("", "test", "ncs:service-modified")

The last line gives me error:
File "/home/dev/.local/lib/python3.8/site-packages/ncs/maapi.py", line 711, in write_service_log_entry
_tm.maapi.write_service_log_entry(self.msock, path, msg, type, level)
TypeError: argument 3 must be confd.Value

Setup:

Ubuntu

NSO v5.5.2

Thank you !

Hello @Maksim12,

NSO is not my specialty, but I'd like to point out some resources for you, which will hopefully prove helpful:

• NSO Developer Hub - YouTube Channel
• Cisco NSO, add Python logic to a service - YouTube Video from Cisco DevNet
• NSO-developer - GitHub repo from Cisco DevNet to share and collaborate around code related to Cisco NSO
• The NSO Developer space on GitHub - Guide / Tutorial
• NSO API Documentation

Hope this helps!

The third parameter should be an instance of ncs.Value, so:

    servicelog = ncs.service_log.ServiceLog(node)
    servicelog.error("", "test", ncs.Value("ncs:service-modified", ncs.C_BUF))
