Graylog collector (v0.5.0) gets hang


(Amit Shah) #1

Hello,

Issue: Graylog collector process shows as running when checked with below commands

  1. /etc/init.d/graylog-collector status
  2. ps -ef | grep graylog-collector
    But actually it is not sending logs when data increase inside log files.

OS: Amazon Linux
OS VERSION_ID=“2017.03"
Graylog Collector Version: 0.5.0.
File: Graylog collector
COLLECTOR_JAVA_DEFAULT_OPTS=”-Xms1024m -Xmx1024m -Djava.library.path=$COLLECTOR_ROOT/lib/sigar"

Thanks,
Amit.
