Inoltre, lo stesso messaggio di avvertenza sullo stato di salute viene visualizzato quando il numero di hot bucket creati per indicizzare i dati in un particolare giorno/ora supera o raggiunge il limite di soglia definito in system/health.conf.
La ragione dietro la creazione di troppi hot bucket
Splunk utilizza i bucket come directory di indice per indicizzare i dati. Quando un evento viene inviato a Splunk per l'indicizzazione, il nuovo hot bucket viene creato per tale evento oppure l'evento viene indicizzato in uno degli hot bucket esistenti in base al timestamp dell'evento e ai vincoli dell'indice.
Fare riferimento ai parametri maxHotBucket, maxHotSpanSecs e quarantinePastSecs di indexes.conf
Pertanto, se l'evento presenta un timestamp precedente/strano che non è accettabile per i bucket esistenti, Splunk creerà un nuovo hot bucket per indicizzare l'evento. Quindi, il numero di hot bucket creati può raggiungere o superare la soglia.
Quando il parametro DATETIME_CONFIG del file props.conf non è impostato in modo esplicito, Splunk tenterà di trovare il timestamp in un evento.
Pertanto, durante l'estrazione del timestamp dagli eventi, se Splunk trova il valore che corrisponde al formato di timestamp valido, analizzerà lo stesso valore dell'ora dell'evento e lo indicizzerà utilizzando solo tale timestamp, il che potrebbe causare la creazione di un nuovo hot bucket da parte di Splunk poiché il timestamp non viene estratto correttamente.
Prendere in considerazione l'aggiunta di attributi timestamp in props.conf per rendere corretto il timestamp di estrazione Splunk. Configurare il riconoscimento timestamp
