In his sordid career, Leon Adato has worked as an actor, bug exterminator, wild-animal remover,
electrician, carpenter, stage-combat instructor, American Sign Language interpreter, and Sunday school
teacher.
Oh, and he works with computers, starting back in 1989 (when you could get a free copy of Windows 286 on twelve 5¼” floppies when you bought a copy of Excel 1.0). In IT, he’s had jobs as a classroom instructor, course ware designer, desktop support tech, sysadmin, and network engineer.
Then, about 25 years ago, he got involved with monitoring, working with a wide range of tools: Tivoli,
Nagios, Patrol, ZenOss, janky perl scripts, OpenView, SiteScope, SolarWinds, Grafana, Zabbix, New Relic, and Kentik. In the course of that work, he's designed solutions for companies that ranged in size from modest (~10 systems); to significant (1,000 - 5,000 systems); to ludicrous (250,000 systems in 5,000 locations).
