I feel Azure Monitor does a fair job. I do feel it is not a streaming service in my opinion. There are advantages to having stream messaging and logging on that level. But for what it is, I feel it does well. My perspective is more based on an Application Insights agent running on a service or an app service and sending the telemetry via the agent, and also doing the filtering of telemetry at the agent level so you are not having a ton of telemetry. I believe Azure Monitor does pretty much the same thing. I have also used tools such as New Relic, and New Relic is a much more robust tool, but that is a different product and you are going to pay for that. It is a different offering altogether. The subscription that we had at the time allowed for a couple gigabytes of telemetry during the month, and I believe that telemetry only lives for about two months. You have to experiment with it to see how much you want to pay. I was not really involved in the pricing. It was more along the lines of we were running up against our limits in terms of the amount of free telemetry or telemetry that we get with our subscription, and so we either needed to scale back or turn specific telemetry types off or do some more sampling. It is nice that those capabilities are there so that you can reduce the amount of telemetry. I cannot really speak to pricing but I do believe that it is somewhat reasonable for Azure Monitor. New Relic is pretty expensive, I believe.
