DevOps Engineer, Tozny
We looked into running our own Elastic Stack, and quickly realized that was a job and specialty within itself. We are a small startup and every dollar counts. Wasting precious and expensive sysadmin time on managing things far out of our project scope really isn’t an option

CEO, BlockGen
Sematext Logs provides us a flexible, extensible and reliable means of monitoring all of our environments in real time
