• Where? https://t.me/ZabbixTech

• Question: Hi team...is there any query where we can get the count of alarms raised per day?

• Answer: Since version 6.0 you can create an API key and then do an JavaScript Script Item to check the information from Zabbix API using time_from and time_till parameters to filter the day before. Didn't tested, just prototyped the idea below, and before trying the code, remember to add the "url" and "apikey" to the item Parameters, (and please use a macro with vault for your apikey), in this case I'd configure the item interval as an scheduled one to run everyday at 1 or 2 AM:

Laboratório de eventos real-time do Zabbix para OpenSearch usando Logstash

TL;DR: O ingestão e atualizaçao dos dados foi feita com sucesso, a PoC terminou no ponto onde o Logstash para o OpenSearch não se mostrou interessante do ponto de vista de não ter recursos (que em pesquisa existem plugins do logstash para a versão proprietária do ElasticSearch) para calcular em novos campos no processo de atualização o tempo de duração dos eventos para facilitar o desenvolvimento de dashboards de apresentação de dados. Concluindo-se assim que seria mais interessante um python no lugar do logstash para executar funções de "update by query".

Composição

• Logstash para processamento dos dados vindos de triggers do real-time export do Zabbix
• OpenSearch para armazenamento e pesquisa
• OpenSearch Dashboards para analise de dados e dashboard
