Sometimes can see significant drop in logs

[Tafsir_Alam (Tafsir)]

Hi All,

From few days I noticed significant drop in the logs. Can see gap in the logs. Nothing unusual found in the logs. Please help me in this.

Graylog version - 2.4.6
Elasticsearch version - 5.6

Thanks in advance

This could be:

• The source not sending data
  • the collector having issues
• something in your network
  • network saturation
  • switch reboot
• something in Graylog
  • reboot
  • high load
• something in Elasticsearch
• reboot
• high load

As you see the list is not short and the investigation is something that you can do from the inside only.
