Além disso, a mesma mensagem de aviso de integridade acima é mostrada quando o número de hot buckets criados para indexar os dados em uma hora/dia específica ultrapassa ou atinge o limite definido em system/health.conf.
A razão por trás da criação de muitos hot buckets
O Splunk usa buckets como um diretório de índice para indexar os dados. Agora, quando um evento chega ao Splunk para indexação, o novo hot bucket será criado para esse evento ou o evento será indexado ao existente um dos hot buckets de acordo com o carimbo de data/hora e as restrições do evento no índice.
Consulte os parâmetros maxHotBuckets, maxHotSpanSecs e quarantinePastSecs de indexes.conf
Portanto, se o evento estiver tendo o timestamp mais antigo/estranho do que o aceitável para os buckets existentes, o Splunk criará um novo hot bucket para indexar esse evento. Assim, o número de hot buckets criados pode atingir ou ultrapassar o limite.
Quando o parâmetro DATETIME_CONFIG de props.conf não estiver definido explicitamente, o Splunk tentará localizar o carimbo de data/hora em um evento em si.
Assim, ao extrair o timestamp dos eventos, se o Splunk encontrar o valor que corresponde ao formato de timestamp válido, ele analisará o mesmo valor que o tempo do evento e o indexará usando apenas esse timestamp, o que pode fazer com que o Splunk crie um novo hot bucket, já que o timestamp não foi extraído corretamente.
Considere adicionar atributos de timestamp em props.conf para fazer com que o timestamp de extração de Splunk seja corretamente. Configure o reconhecimento de timestamp
