Ett problem med ElasticSearch-data  

Kommandon körs på PowerFlex Manager CLI med delladmin-kontot .

Steg 1 = frigör utrymme i elastisk sökdatabas (maxstorlek ska vara 5G)

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

Om det finns många snmp-trapindex är det ok att ta bort äldre traps om du är ok med det:

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

Eller så kan du ta bort dem alla med kommandot nedan:

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

Steg 2 = ta bort elastiska sökloggar.

• 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

Steg 3 = Ta bort ALL data i ElasticSearch: 

*Varning: Kunden förlorar alla historiska aviseringar, prestandamått från resurser och syslog-data.

• curl -XDELETE localhost:9200/_all

Kontrollera statusen och stoppa rsyslog-tjänsten.

systemctl status rsyslog

systemctl stop rsyslog

Försök igen och starta syslog-tjänsten:

systemctl start rsyslog
