** [tickets:#1918] AMF: Informative logging**
**Status:** unassigned
**Milestone:** 5.1.FC
**Created:** Fri Jul 15, 2016 11:30 AM UTC by Minh Hon Chau

Some error/warning logging in AMF currently does not give enough information
about unexpected situation.
For example:
1- LOG_ER("%s: invalid node state %u", __FUNCTION__, node->node_state);
-> it should tell which node name/id is in invalid state
2- LOG_ER("Wrong sg fsm state %u", su->sg_of_su->sg_fsm_state);
-> it should tell the sg name is in wrong fsm state
3- LOG_ER("Invalid node_name. Check node_id");
-> it should tell the node name in msg that amfd can not find
4- LOG_ER("Internal error, could not send message to avnd");
-> it should tell at least node id of which avnd that msg can not be sent to
5- LOG_ER("%s: no susis", __FUNCTION__);
-> which su has no susis
6- LOG_ER("avnd_di_msg_send FAILED");
-> it's helpful to know which msg is failed to sent out, so we can know which
msg is missing at amfd
...
As the logging is informative, it could help debugging in running system where
the fault sometimes could not be reproduced, or we can identify the fault
straight away without tracing enquiries
This ticket will scan through amfd/amfnd file by file and add more information
in error/waring cases. It's started at 5.1 FC and could be continued in next
releases. Some rules:
1. Log must tell the object that error happens on
2. Log must give error code if it fails at checking return code
3. When failed to send msg, log the msg type and object that msg carries (if
any)
4. ...
