Satsite Monitoring with Zabbix

Introduction

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.

Minimum Software Requirements

The following rpms or newer must be installed:

  • yate-sdr-1.1-1_r214_r477_8217_svn.mga5.noarch.rpm
  • satsite_utilities-1-1_8220_svn.mga5.x86_64
  • yate-bts-satsite-1.1-1_r3061_prot.mga5.noarch.rpm
  • yate-common-1.7-1_r110.mga5.noarch.rpm

Please note that yate-bts-satsite and satsite_utilities won’t be part of any public releases as they are hardware specific.

Configurations

Zabbix Server configurations:

If you don’t havr Zabbix server installed, please refer to:

1.Import yate-satsite template:

  • Open this link: Zabbix YateRAN Templates
  • Save the template .xml
  • Open Zabbix frontend http:///zabbix and login with (Admin / zabbix )
  • Navigate to Configurations -> Template -> Import -> select the file .xml and keep the rules to the default -> Import
  • You will have a message that it was imported successfully.

2. Add the satsite(s) as host:

  • From Zabbix frontend, navigate to Configuration -> Hosts -> Create host
  • In the Create host page:
  • From Host tab
    • set Hostname to yate-sdr-ybts-
    • Optionally set visible name for how you will see the host
    • Create new group for Satistes or use any predefined group
    • Set the Satsite IP address
    • Make sure the host is enable

3. Apply yate-satsite template:

You can apply the template for each host or you can apply it to the host group.

  • To apply the template to each host: Configurations -> hosts -> select the host -> Templates tab -> Link new templates -> select yate-satsite -> add -> add

  • To apply the template to the host group: Configurations -> host groups -> templates -> select the template yate-sdr -> apply

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)

Satsite triggers

ErrorSeverity
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
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

Please note that all these triggers clears the alarm when if the error was resolved.
