yes

agent conf:

# Log File
LogFile=/var/log/nxagentd

# IP white list, can contain multiple records separated by comma.
# CIDR notation supported for subnets.
MasterServers=127.0.0.1
SubAgent=ssh.nsm
SubAgent=ping.nsm
[SSH]
ConfigFile = /etc/nxagentd-ssh-config
MaxSessions=500



even tried adding MaxSessions=500 in /etc/nxagentd-ssh-config....

no luck

Hello,
yes i have a lot of ssh metrics configured.
i tried to set MaxSessions to 100 and 500 but the log is full of error message.

it is no agent proxy, agent is netxms server itself.

Hello,

i noticed in agentd log:


Too many communication sessions open - unable to accept new connection


and i noticed that my ssh dci's dont update ...

i read the manual and forum but could not find a solution.

I try to connect to ubiquiti gear with ssh but get the error in the log on the client side:
Exit before auth: No matching algo hostkey
in Netxms i get ssh connection not available.

if i connect with tools, connect, ssh, it asks me user and password and connects.

My goal is to have passwordless connection to ubiquiti devices...

Is there a howto ? I tried several times but no luck....

Hello,

it works perfect!!

thank you

Hello,

i have a lot of Aruba APs i want to monitor, problem on discovery:
only 1 is discovered:
log:

2023.08.08 16:57:42.286 *D* [poll.discovery    ] AcceptNewNode(10.66.180.129): IP address xxxxxxxxxxxon interface BR0 matches existing node xxxxxxxxxxxxx [1678]

2023.08.08 16:57:42.287 *D* [poll.discovery    ] AcceptNewNode(10.66.180.131): filter flags=0000

how can i avoid this problem ? The Aruba AP have all the same ip on BR0 interface...

Hello,

does someone monitor a large number of ubiquiti gear?

I would like to use netxms for monitoring but,
Aircontrol2 -- discontinued
UNMS -- cannot monitor 3rd party gear

Tested netxms and i think it can do all with proper configuration.
Problem: ubiquiti has different snmp oids, maybe someone has templates for all different Products?

Thanks.
