SatSite Monitoring with Zabbix

You are here:
< All Topics

This Guide will explain how to use Zabbix Server for Monitoring SatSites.

It will provide PSU and Chrony readings during normal operation and show triggers when there is a problem.

Note: If Zabbix and the SatSite are not already configured , please refer to LabKit/SatSite Monitoring with Zabbix – Basic Configurations
Note: To configure eNodeB monitoring, please refer to eNodeB Monitoring with Zabbix

Monitoring Normal operations

During the normal operations, you can find PSU and Chrony related items.

From Monitoring -> latest data -> filter with the application satsite.


Chrony is the service used in satsite for NTP.

  • Chrony Delay: This is the total of the network path delays to the stratum-1 computer from which the computer is ultimately synchronized. Root delay values are printed in nanosecond resolution.
  • Chrony Dispersion:​ This is the total dispersion accumulated through all the computers back to the stratum-1 computer from which the computer is ultimately synchronized. Dispersion is due to system clock resolution, statistical measurement variations etc. Root dispersion values are printed in nanosecond resolution.​
  • Chrony Skew:​ The estimated error bound on the frequency.​


Satsite got multiple Power supplies:

  • VA: Power supply output for the LNA (long noise amplifier) and the preamplifier.
  • VB: Power supply output for the BladeRF (if VA is zero, VB must be zero and vise versa).
  • 12 MB: Power supply for the motherboard of the computer inside the SatSite.
  • 28 RFPA power supply for the Radio Frequency Power Amplifier (amplifier is turned off, there must still be a voltage between 10V and 12V).

RF Indicator

RF Indicator is a graph that gives an idea of the RF situation by showing 4 items:

  • Noise
  • SNR
  • RSRQ
  • UL FER

The better these values are, the line in the graph goes up (maximum is 15) and the worse they are, the lines reach zero (The minimum). Nevertheless, the real values can be read using ENB application items.

To view the graph: Monitor -> graph -> Yate ENB RF Indicator.

Satsite triggers

Voltage stopped automatically because I28V is too highHigh
Intensity of the current in the 12V power supply exceeded the limit [Main board problem]High
Intensity of the current from Vb is too high, preamplifier and the LNA stop working [20 Preamp or LNA damaged]Disaster
Intensity of the current supplying the BladeRF is too high, BladeRF had to be shut down [BladeRF damaged]Disaster
Power supply unit temperature out of rangeWarning or Disaster
Power amplifier temperature out of rangeWarning
Power amplifier RF fault, usually a problem with RF connectors, cables, or antennas [Antena or cable damaged]High
The power supply unit has shut down everything but the main board to prevent damage to itself [I2C device damaged]Disaster
Antenna or cable damagedHigh
Satsite Chrony got high Skew valueHigh
Satsite has switched to the backup coreWarning
Note: All triggers clears the alarm when if the error was resolved.
