					<description><![CDATA[Why is my name showing as 0x6d79206e616d65? Strings in Prometheus are full UTF-8, however not all byte sequences are valid UTF-8. For example the byte 0xff cannot appear in a valid UTF-8 string. What does this have to do with SNMP? If we get arbitrary bytes that could in principle be anything, then we have [&#8230;]]]></description>

					<description><![CDATA[Not all numbers in SNMP are exposed as numbers, which is why regex_extracts exists. As a metrics-based monitoring system Prometheus works off numbers, with labels to help group related things. SNMP's data model is surprisingly close to the Prometheus data model, with SNMP table indexes basically being Prometheus instrumentation labels. So in theory once you [&#8230;]]]></description>

					<description><![CDATA[Many problems with the snmp_exporter turn out to actually be issues elsewhere, but how can you tell? SNMP can be bit mysterious at times, and sometimes the device just doesn't respond or gives weird results. You might see a scrape error like: An error has occurred during metrics gathering: error collecting metric Desc{fqName: "snmp_error", help: [&#8230;]]]></description>

					<description><![CDATA[Prometheus isn't limited to monitoring just machines and applications, it can provide insight for any system you can get metrics out of. That includes network devices, so let's look at how to monitor SNMP. First off, let's install and run the SNMP exporter: wget https://github.com/prometheus/snmp_exporter/releases/download/v0.6.0/snmp_exporter-0.6.0.linux-amd64.tar.gz tar -xzf snmp_exporter-0.6.0.linux-amd64.tar.gz cd snmp_exporter-* ./snmp_exporter If you visit :9116/ you [&#8230;]]]></description>
