SatSite Monitoring with Zabbix
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
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.
PSU
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
| Error | Severity |
|---|---|
| Voltage stopped automatically because I28V is too high | High |
| 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 range | Warning or Disaster |
| Power amplifier temperature out of range | Warning |
| 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 damaged | High |
| Satsite Chrony got high Skew value | High |
| Satsite has switched to the backup core | Warning |
Note: All triggers clears the alarm when if the error was resolved.
