Side by side
A hosted log aggregation and search service with dashboards and alerts, owned by SolarWinds.
A log aggregation system that indexes only labels and stores log content cheaply in object storage, queried from Grafana with LogQL.
The product has seen little visible development in recent years, and newer services offer more for the price.
Full-text search over unindexed content is slow at scale, and running it distributed is complex.
