Like the Amish but with more technology? I have troubleshooted this issue for several days, noticed that it is not a simple timeout, my steps are: Start snmp_exporter on a Linux server(172.30.50.121) in the same LAN with target QNAP(172.30.50.104): Run a script which request to snmp_exporter on 172.30.50.121: It will report timeout in minutes, and the snmp_exporter logged: Those look identical on the wire, so this is probably some networking issue on the box itself. Prometheus provides an official SNMP exporter, A.K.A snmp_exporter, which can be used for monitoring devices which support SNMP, such as switches, routers, firewall, etc. This will generate a configuration file called snmp.yml. Make changes based on OIDs collected in the above section, the original generator.yml sample can be referred as the blueprint. After loading the MIB, more information about switch interfaces can be seen as below: It is time to find MIBs for CPU and memory stats, Again, search CPU and memory with http://www.net-snmp.org/docs/mibs, but this time, no result can be found, Lets google Cisco switch cpu snmp mib to locate the CPU usage inforamtion at first. And that's the point when the process fails. After you installed these packets, you must follow the configuration steps below. This knowledgebase contains questions and answers about PRTG Network Once the generator configuration file is ready, it is time to generate the configuration file for exporter: After running above commands, the exporter configuration file snmp.yml is generated. How to scrape multi modules in one request? More than 500,000 users rely on Paessler PRTG every day. Good resources for information about SNMP on Linux systems are the articles on Sijoe Web's: SNMP Server (snmpd) and Client (snmp) Installation and Configuration in Debian and on ubuntuusers Wiki: SNMP (German). For example: Create your generator.yml in ./snmp_exporter/generator.yml or use the example provided., The config generator uses NetSNMP to parse MIBs and generates configs for the snmp_exporter using them, so we have to make sure the MIBs are in the right path. contributing them to https://github.com/prometheus/snmp_exporter/tree/main/snmp-mixin. # sec.name source community First I added the following module setting to blackbox.yml because I've never used ICMP monitoring before.

Learn more about the CLI. Second, if youre not using ready-made configurations shipped with the snmp_exporter, the generator, which uses NetSNMP to parse the MIBS and generate the snmp.yml configuration file to be used by the snmp_exporter, is a necessary component.
