Reliable and Cost-Effective Tool for Log Tracking with Excellent Support

We’ve been using Last9 primarily for log tracking, and it has been quite smooth so far. The platform makes it easy to view, filter, and correlate logs, which really helps when debugging issues. One of the biggest advantages we’ve seen is the cost efficiency, it’s comparatively less expensive than other observability tools we’ve used or evaluated.

A critical piece of our new telemetry system

last9's sales/support team was incredibly helpful in setting us up / getting us started using the platform. It has been intuitive and most importantly powerful to use. Has done a great job helping us cut through the massive amounts of telemetry data our system produces, and the insights we've gained from it have already highlighted bugs in our system and helped us identify and resolve outages before they got out of hand. Last9's high cardinality data features made it stand out from other products we considered.
