Et problem med ElasticSearch-dataene  

Kommandoer køres på PowerFlex Manager CLI ved hjælp af delladmin-konto .

Trin 1 = frigør plads i elastisk søgedatabase (maks. størrelse skal være 5G)

• curl 'localhost:9200/_cat/indices?v’

Hvis der er mange snmp-fældeindekser, er det ok at slette ældre fælder, hvis du er ok med det:

• curl -X DELETE localhost:9200/snmp-traps-YYYY.MM.DD (this deletes a specific date)

Eller du kan slette dem alle ved nedenstående kommando:

• curl -X DELETE 'http://localhost:9200/syslog* [localhost]'

Trin 2 = fjern elastiske søgelogfiler.

• sudo systemctl status Elasticsearch
  sudo systemctl stop Elasticsearch
  
  cd /var/log/elasticsearch (note: Do not delete vxfm-es-cluster.log)
  rm -rf *log.gz*
  rm -rf *gc.log*
  rm -rf *showlog.log*
  
  Systemctl start Elasticsearch
  sudo systemctl status Elasticsearch

Trin 3 = Slet ALLE data i ElasticSearch: 

*Advarsel: Kunden mister alle historiske advarsler, ydeevnemålinger fra ressourcer og syslog-data.

• curl -XDELETE localhost:9200/_all

Kontroller status, og stop rsyslog-tjenesten.

systemctl status rsyslog

systemctl stop rsyslog

Prøv igen, og start syslog-tjenesten:

systemctl start rsyslog
