Many of the clients I speak with on a regular basis want to simplify their monitoring technologies. It’s too time consuming, error prone, and complex to run much of the software deployed currently. Many of them want to outsource the management, some of them want SaaS models, and others want appliance or simple monitoring systems. Obviously you make sacrifices when you take this approach, but does it really affect downtime? Leveraging agentless monitoring is a good way to increase coverage and reduce complexity involved in agent management. In many cases, and on critical systems agents are required. This is something that is discussed in a note which was published a few days ago: How to Augment APM with conventional monitoring
Customer demand is changing a lot of portfolios inside companies, and vendors are responding. I am seeing smaller vendors go up against large incumbent solutions in a more regular manner. I believe this trend will continue, and one of my upcoming research notes on SaaS monitoring solutions will provide a good overview of the options if you want to have control, but simplify the technology and implementation.
Alongside this trend there is a strengthening interest in open source monitoring tools, saving cost, and simplifying management of the tools. The ease of open source is somewhat of a misnomer, which is why I am close to publishing 2 notes on open source and commercial open source options.
