Astor heartbeat error - TANGO Controls

# 7 years ago
sriggi	Dear all, does anybody experience this problem with Astor? `tango/admin/muoni-wn-01 has received a DevFailed : No heartbeat from dserver/starter/muoni-wn-01 HostStateThread.StateEventListener on tango/admin/muoni-wn-01 muoni-wn-01 Tango exception Severity -> ERROR Desc -> No heartbeat from dserver/starter/muoni-wn-01 Reason -> API_NoHeartbeat Origin -> ZmqEventConsumer.checkIfHeartbeatSkipped()` The problem persists if I drop down the iptables on the host. Apparently Astor seems to work, because it allows to see controlled device, switch them on/off and update the GUI correspondingly. Did I forget to turn on or configure some property in the Starter? For example UseEvents is set to false in Starter (actually I do not understand what this property is doing…). Any hints? Thanks for the help, Simone PS: OS: SL6, Tango version 9.2.2, Astor 6.7.0 ************************************************************** Simone Riggi INAF, Osservatorio Astrofisico di Catania Via S.

Dear all,

does anybody experience this problem with Astor?


tango/admin/muoni-wn-01  has received a DevFailed :	No heartbeat from dserver/starter/muoni-wn-01
HostStateThread.StateEventListener on tango/admin/muoni-wn-01
muoni-wn-01
Tango exception
Severity -> ERROR 
Desc -> No heartbeat from dserver/starter/muoni-wn-01
Reason -> API_NoHeartbeat
Origin -> ZmqEventConsumer.checkIfHeartbeatSkipped()

The problem persists if I drop down the iptables on the host.
Apparently Astor seems to work, because it allows to see controlled device, switch them on/off and update the GUI correspondingly.
Did I forget to turn on or configure some property in the Starter? For example UseEvents is set to false in Starter (actually I do not understand what this property is doing…).
Any hints?

Thanks for the help,

Simone

Pascal	Hi The problem is not on Astor. It could be on java client API. which release of JTango ? Or from your network configuration.How is defined your TANGO_HOST ? Pascal

Reynald	Hi Simone, The UseEvents property from the starter is useful only if you are using an old version of Tango, which I guess is not your case. This property is used to tell the Starter to monitor the state of the notify daemon process which used to be required to send events in the previous versions of Tango. It also tells the starter that it should start up the notify daemon at startup if it's not yet running. This is no longer needed for the Tango versions using ZMQ to send events.

sriggi	Dear Pascal & Reynald, many thanks for the useful info. I'm using latest Tango v9.2.2 (which haves JTango-9.0.7 if I'm not wrong). TANGO_HOST is set to: muoni-storageXXXX:10000 where muoni-storageXXXX is the hostname of the cluster node where MySQL server and TANGO DB are running. I have no Java device server in the system. Only one C++ device server for testing at present. Starter and astor were run from a different node.
