Re: AgentX reconnect time
It's not working in 5.7.3 either and w/o the possibility to us "-c" option
for the agent.
So it's broken!!

Re: AgentX reconnect time
Hi Mostafa,
which version of net-snmp are you using?
In 5.8 you can use the "-c" option which works, but I also found a bug in
it using the default paths
*# ./mysubagent -h *
USAGE: ./mysubagent [OPTIONS]
OPTIONS:
-c FILE[,...] read FILE(s) as configuration file(s)
-Cdo not read the default configuration files
*# cat agentx.conf *
[snmp] logTimestamp 1
agentXPingInterval 5
*# ./mysubagent -C -c agentx.conf -f -x /var/agentx/master *
2019-02-22 07:23:40 Warning: Failed to connect to the agentx master agent

2019-02-22 07:23:45 Warning: Failed to connect to the agentx master agent
(/var/agentx/master):
2019-02-22 07:23:50 Warning: Failed to connect to the agentx master agent
(/var/agentx/master):
The name of the agentx config file can be agentx.conf or agentx.local.conf
and it should be in one of this directories
$HOME/.snmp
/usr/etc/snmp
/usr/lib/snmp
/usr/share/snmp
/var/lib/net-snmp
or you can use the SNMPCONFPATH
AND HERE comes the bug!! Using SNMPCONFPATH or the default path, you will
get "Warning: Unknown token: agentXPingInterval." and the timeout will be
set to the default value of 15.
I will file a bug on this!
*# SNMPCONFPATH=$PWD ./mysubagent -f -x /var/agentx/master*

Please see the followin
RE: AgentX reconnect time
Thank you for your reply, Anders.
I created an agentx.conf file with this single line:
agentxPingInterval 5
I tried putting agentx.conf into one the following directories to no avail:
/var/agentx/
/var/snmp/
Var/net-snmp/
Where should the agentx.conf file go? I did a search on this topic and couldn’t
find an answer.
It is still 15 seconds of disconnection.
Thanks again,
Mostafa

Hi Mostafa,
you need to set it in the config file for your agentx(e.g agentx.conf), not in
snmpd.conf

AgentX master disconnected us, reconnecting in 15
I would like to reduce this time to 5 seconds.
Is this time specifieded in agentXPingInterval as described here?
http://www.net-snmp.org/docs/man/snmpd.conf.html
However if I add agentXPingInterval 5 to the snmpd.conf file, I get this error:
/var/snmp/snmpd.conf: line 35: Warning: Unknown token:agentXPingInterval.
I found this code in agentx_config.c which leads me to believe that this value
is hardcoded and not set in any configuration file. So changing it requires
editing and recompile of the code.
#ifdef USING_AGENTX_SUBAGENT_MODULE
/*
* tokens for master agent
*/
if (SUB_AGENT == agent_role) {
/*
* set up callbacks to initiate master agent pings for this session
*/
netsnmp_ds_register_config(ASN_INTEGER,
netsnmp_ds_get_string(NETSNMP_DS_LIBRARY_ID,
NETSNMP_DS_LIB_APPTYPE),
"agentxPingInterval",
NETSNMP_DS_APPLICATION_ID,
NETSNMP_DS_AGENT_AGENTX_PING_INTERVAL);
/* ping and/or reconnect by default every 15 seconds */
netsnmp_ds_set_int(NETSNMP_DS_APPLICATION_ID,
NETSNMP_DS_AGENT_AGENTX_PING_INTERVAL, 15);
}
#endif /* USING_AGENTX_SUBAGENT_MODULE */

Mostafa
