# ostr.io SNMP Monitoring vs Competitors: Honest Comparison

## Frequently asked questions

### What is ostr.io SNMP monitoring?

ostr.io is an external monitoring service that polls your servers over SNMPv2c from outside, on an independent path. It reads health metrics — uptime, SSH sessions, processes, system load, CPU, HDD/SSD/RAM/Swap usage, and interfaces — and emphasises double durability (an off-box path plus dual-frequency checks). It recommends securing the agent with a random community and an OID allowlist.

### ostr.io vs LibreNMS or Zabbix — which should I choose?

Choose ostr.io for independent, off-box durability with zero maintenance — nothing to host or operate. Choose LibreNMS or Zabbix for deep custom dashboards, on-prem control, and large-fleet flexibility, accepting the operational burden that comes with self-hosting. Many teams run both: a platform for depth, ostr.io for the independent durability layer the platform can't provide itself.

### What SNMP version does ostr.io use?

ostr.io monitors over SNMPv2c. Because v2c uses a cleartext community, it recommends hardening the agent with a random (non-default) community string and an OID allowlist, and scoping the firewall to the poller's source. That way the external check reads only the health metrics it needs, with a bounded, read-only footprint on the device.

### When should I choose an external service over a self-hosted platform?

Choose external when you lack ops bandwidth, want an independent alerting path that survives infrastructure trouble, or need to close a self-hosted platform's self-monitoring blind spot. Choose (or add) a self-hosted platform when you need deep custom dashboards, on-prem data residency, or coverage well beyond the health-metric set. Often the best answer is both together.
