I was looking around for options and came across LogDNA. In terms of pricing, they are similar to SumoLogic. However, they offer the ability to pay for only what you use rather than for a specific log amount. For some use cases, I can imagine this would save some money and for others be prohibitive.
I’ve been impressed with their product and find the interface to be the best of the bunch of companies who will sign BAAs so thought I’d share.
