Niagara BACnet Audit

BACnet Network and Device Health Audit

A one-off live snapshot of BACnet poll service and device health. This is not trend data. It is the current state of the network at the time the tool was run.

How to read this report

Busy time is not the same as health. A port can show low busy time and still miss its configured polling targets. Low busy time only means the poll threads are not continuously occupied. It does not prove that values are updating on schedule.

This report now has two layers: BACnet port health and BACnet device health. Port health tells you whether the network polling layer is keeping up. Device health tells you which BACnet devices are disabled, down, faulted, stale, or unreadable at this snapshot.

Top Findings

  1. BACnet IP port ipPort is UNKNOWN due to METRIC_PARSE_FAILED.
  2. BACnet MSTP port Mstp_2000 is WARNING due to NORMAL_CYCLE_SLOW.
  3. BACnet MSTP port Mstp_3000 is WARNING due to FAST_CYCLE_SLOW.
  4. BACnet MSTP port Mstp_4000 is WARNING due to SLOW_CYCLE_SLOW.
  5. BACnet IP port EthernetPort is UNKNOWN due to METRIC_PARSE_FAILED.
  6. 51 real BACnet device(s) found after excluding internal BACnet child objects.
  7. 0 device(s) have duplicate BACnet Device ID information.
  8. 0 device(s) have duplicate BACnet network/MAC address information.
  9. 0 likely retired/stale station object(s) found.
  10. 0 device(s) have alarm-related status.
  11. 0 device(s) down, faulted, or stale.

BACnet Port Health

These cards judge the BACnet poll service layer using cycle time, configured polling rates, busy time, point count, fast poll dominance, and whether polling is enabled.

ipPort

IP BACnet port
UNKNOWN

Primary Finding

METRIC_PARSE_FAILED

Plain English Summary

The tool could not read enough live BACnet poll data to judge this port reliably.

What This Means

Some required BACnet poll service values were missing or could not be parsed.

Why It Matters

Without the core poll timing values, this snapshot cannot safely say whether the port is healthy or unhealthy.

Recommended Action

Check that the poll service is present and readable, then review the raw output file for missing or unreadable metrics.

Mstp_2000

MSTP BACnet port
WARNING

Primary Finding

NORMAL_CYCLE_SLOW

Plain English Summary

This BACnet MSTP port is online and responding, but it has warning signs.

What This Means

The port is only 19.0% busy, so the JACE is not obviously overloaded. Normal polling is taking 45.3s against a 30.0s target. Fast polling makes up 64.0% of total polling, which can pressure slower BACnet networks.

Why It Matters

A low busy percentage does not automatically mean the BACnet network is healthy. The poll service can be lightly loaded and still miss its configured polling targets.

Recommended Action

Review which points are assigned to fast polling, then check for slow responding or unreliable devices on this MS/TP trunk.

MSTP BACnet port
WARNING

Primary Finding

FAST_CYCLE_SLOW

Plain English Summary

This BACnet MSTP port is online and responding, but it has warning signs.

What This Means

The port is only 18.0% busy, so the JACE is not obviously overloaded. Normal polling is taking 27.6s against a 20.0s target. Fast polling is taking 6.6s against a 5.0s target. Slow polling is taking 67.9s against a 45.0s target.

Why It Matters

A low busy percentage does not automatically mean the BACnet network is healthy. The poll service can be lightly loaded and still miss its configured polling targets.

Recommended Action

Check for slow responding devices, token passing delays, retries, wiring issues, or unnecessary polling load on this MS/TP trunk.

WARNING

Primary Finding

SLOW_CYCLE_SLOW

Plain English Summary

This BACnet MSTP port is online and responding, but it has warning signs.

What This Means

The port is only 0.0% busy, so the JACE is not obviously overloaded. Slow polling is taking 60.0s against a 30.0s target.

Why It Matters

A low busy percentage does not automatically mean the BACnet network is healthy. The poll service can be lightly loaded and still miss its configured polling targets.
