Experience

  • Zabbix ETL Process (Development)

    A Python-based extract transfer and load system for Zabbix. This allowed for a parent Zabbix server to be set. Anything changed within this set parent server would be eventually consistent with all other Zabbix servers running in any available region. This would sync metric settings, alert settings, pager duty settings, etc. There were many challenges to this project as not all elements to a "Zabbix Server" are exposed to the API. The system would also not update any elements that have not changed utilizing a sha256 diff system I had built into the import mechanism for the least amount of IO/CPU stress on these systems.
