Hi! I am having this error: [inputs.snmp] Error in plugin: agent udp://192.168.20.103:161: performing get on field SNMPv2-MIB::sysName: error reading from socket: read udp 192.168.2.13:60574->192.168.20.103:161: recvfrom: connection refused And couldn’t figure out what is happening. Sometimes fr…

Well as the message says, Telegraf can not establish a UDP “connection” to the given host/port! :slight_smile: Packetfilter? Typo in IP or port? Authentication missing or wrong?

Hi @srebhan ! The connection works perfect until fails. I run it with --test option an works fine, here is a partial output: > SNMPv2-MIB::system,SNMPv2-MIB::sysContact=Backend\ de\ Aseguramiento,SNMPv2-MIB::sysDescr=Hardware\ management\ system,SNMPv2-MIB::sysLocation=ARBBCWP\ EL\ TALAR\ RUTA\ P…

I got the problem so I did this tests: ARBBCWP_GDE_DSS01:/home/paas/telegraf/test # ping 192.168.20.103 connect: Resource temporarily unavailable ARBBCWP_GDE_DSS01:/home/paas/telegraf/test # snmpget -v3 -Oa -l authPriv -u -a SHA -A "" -x AES -X "" 192.168.20.103 SNMPv2-MIB::sysName.0 snmpget: Unkn…

More tests: Runing like this: /usr/bin/telegraf -config /home/paas/telegraf/conf/telegraf.conf -config-directory /home/paas/telegraf/test --once I got the problem. But runnig like this: /usr/bin/telegraf -config /home/paas/telegraf/conf/telegraf.conf -config-directory /home/paas/telegraf/test -…

Hi! After many, many test I got to this. Looks like some limit in my SO configuration. If while running telegraf I check netstat, I got one of this lines for each inputs.snmp plugin: 2024-09-23T11:14:33Z I! Starting Telegraf 1.32.0 brought to you by InfluxData the makers of InfluxDB 2024-09-23T1…

Hi! @srebhan finally I found the root cause here: Why does ping fail with the error “connect: Resource temporarily unavailable”? This is my SO configuration: net.ipv4.ip_local_port_range = 60000 65000 That leaves 5001 connection ports. My final configuration would have around 15000 inputs.s…

Did you try to set unconnected_udp_socket = true?

Hi @srebhan ! I set all my plugins with interval = “24h” with unconnected_udp_socket = true and worked, this morning the ports are free. But the problem is still there. At midnight when all the “24h” plugins start, they use all the port available (5001) and the next plugin has no port. I have …

Well, it didn´t work. It seems that although the ports are freed after use, Telegraf starts all plugins at once not considering the “collection_offset” setting therefore at 00:00 when the “24h” interval starts, one port per plugin is needed. I set net.ipv4.ip_local_port_range = 1024 65535 so n…

I think this was solved in the other thread by setting unconnected_udp_socket = true.
