I have multiple technologies running on a single PC like Hadoop, HBase and all. So I have written that many config files. The way I deploy them is by running a for loop over all the configs and deploying them one by one in a separate logstash instance in a thread. These configs output ERROR events to riemann:
for(all configs) do (bin/logstash -f config &) finish
But this way not a single config works. So I ran a single losgatsh instance on a single config and it worked. Can you please tell me why multiple logstash instances on a single PC are not working?
