Hello.
I am trying to use passive monitoring with some binaries that cannot be
modified to integrate active monitoring. The thing is, for some binaries it
works, for some others the call to saAmfPmStart_3 is failing with
SA_AIS_ERR_NOT_EXIST.
With the same imm.xml, I just change the saAmfCtRelPathInstantiateCmd to point
to a different binary and it fails.
The binaries do get executed. In some other occasions, the error was caused by
the binary not being run. But the binaries do get launched by the
InstantiateCmd. When the saAmfPmStart_3 fails, the CleanupCmd is called and the
binaries get killed, therefore, the PID points to the correct place.
The opensafd log does not show any info other than the SU failover message.
I've enabled the logging in the amfpm binary and this is the output:

As you can see, everthing is seemingly correct up till the last moment, where
the error code 12 (== SA_AIS_ERR_NOT_EXIST) causes it to fail. In amf_agent.cc
there's this code:
rc = static_cast<SaAisErrorT>(ava_mds_send(cb, &msg, &msg_rsp));
if (NCSCC_RC_SUCCESS == rc) {
TRACE_2("AMFAGENT ava_mds_send success");
osafassert(AVSV_AVND_AMF_API_RESP_MSG == msg_rsp->type);
osafassert(AVSV_AMF_PM_START == msg_rsp->info.api_resp_info.type);
rc = msg_rsp->info.api_resp_info.rc;
That's where the rc gets set to SA_AIS_ERR_NOT_EXIST. I've found five places
where msg_rsp->info.api_resp_info.rc gets assigned SA_AIS_ERR_NOT_EXIST, all of
them in clms_evt.cc but I'm afraid I cannot pinpoint the exact place where it
happens in this occasion because the log messages there do not appear anywhere.
Do you know what could be causing this issue?
Thanks.
