Lambda deployed in VPC

My plan was to use nginx to proxy reqests to elasticsearch. I setup a nginx box with an elastic IP and then configured elasticsearch to only allow access from that IP…. Read more »

Securing AWS ElasticSearch

So this was a fun problem, ElasticSearch on AWS in it’s current form is completely public and not secured within my VPC. It appears that first you have to put in a deny statement to lock off access and then you add in the roles / users that have access. But once you do this you now… Read more »

Zabbix Warning: Less than 25% free in the configuration cache

Because I always forget how to fix this issue and have to research it every time I come across it, I thought it was time to blog about it. So this morning I got the error on our new-ish zabbix server that our config cache was getting full. This didn’t surprise me since we’ve been adding… Read more »
