Network monitoring
Measure path health from the places your users and services actually sit. Network agents run active tests on a schedule, test each other as a mesh, poll and receive SNMP from network devices, and build a topology you can compare over time.
- Test types
- Nine, from ping to bandwidth
- Agent
- Linux and Windows, written in Rust
- SNMP
- v2c and v3 polling, v1 to v3 traps
- Views
- Topology and path analysis
Test types
Each test runs on a schedule from one or more network agents.
| Test | What it tells you |
|---|---|
| Ping | Reachability, round-trip latency and packet loss |
| Traceroute | The hops on the path and where latency or loss appears |
| TCP connect | Whether a port accepts connections, and how fast |
| UDP | Whether a UDP service answers |
| DNS | Resolution time and the answers returned |
| HTTP | Status, timing and response assertions, including mutual TLS |
| TLS certificate | Certificate validity and days to expiry |
| MTU | The largest packet the path carries without fragmenting |
| Bandwidth | Throughput between agents (off by default) |
Beyond single tests
Agent mesh
Agents test each other, so you see latency and loss between every pair of sites rather than only towards one target.
SNMP polling
Poll switches, routers and firewalls over SNMP v2c or v3 (with authentication and privacy) for reachability, interfaces and counters.
DocumentationSNMP traps
Turn on the trap listener and point devices at the agent to receive v1, v2c and v3 traps as events, with a registry of the devices that sent them.
DocumentationLAN discovery
Optional discovery over LLDP, ARP and mDNS finds the devices around each agent. It is off until you enable it.
Topology and path analysis
A topology built from discovery and test results, and path analysis that compares a path with an earlier one to show what changed.
DocumentationEvents and changes
Changes in paths, devices and test results are recorded as events, so you can line a slowdown up with what changed.
Documentation
Getting started
- 01
Register an agent
Under Network, then Agents, register an agent to get its connection key.
- 02
Install it
Use the Windows installer or the Linux package. The agent connects outbound to VerOps.
- 03
Create tests
Pick a test type, a target, the agents to run from and a schedule.
Limits worth knowing
- The network agent runs on Linux and Windows. macOS is not supported.
- Discovery, SNMP and bandwidth tests are off by default and are enabled per agent.
- These are active tests and device polling. Plan around them rather than around passive flow analysis.
