Hey, as Daryl Brown already mentioned, the EH.EH_HOSTDST / EH.EH_HOSTSRC / AH.AH_HOSTDST / AH.AH_HOSTSRC fields contain the agents that the job was using (eh = running, ah = ended; dst = target for the job or destination agent for JOBF, src = src agent for JOBF).
Having the agent name, you can then refer to the ACTEX table that lists the reported hostname/ip for the agents that is seen in Administration > Agents. Keep in mind that hostnames there usually only contain the local hostname (`testserver`) and not the FQDN (`testserver.company.example.com`). Also note that the hostname should reflect whatever you may have set in the agent ini under [VARIABLES] -> UC_EX_IP_ADDR (e.g. to get the FQDN).
The agent's OH_IDNR is in ACTEX.ACTEX_OH_IDNR, the agent name is also reported in ACTEX.ACTEX_HOST. Hostname is ACTEX.ACTEX_HOSTNAME, IP is in ACTEX.ACTEX_IPADDR. There is also other potentially useful information about agents in this table.
