eG Enterprise vs PoWA

eG Enterprise is an application and infrastructure monitoring platform from eG Innovations, founded in 2001 and headquartered in Singapore. It correlates user experience, application behavior, and infrastructure health to help identify why applications are slow. Transaction tracing follows Java and.NET activity across application tiers, including errors, database queries, and remote service calls. Agentless digital user experience monitoring identifies slow pages, affected locations, and whether delays arise in browsers, networks, content, or server processing. The Web App Simulator records and replays journeys, runs scripts from multiple locations, and captures failure screenshots. Coverage spans more than 650 technologies across applications, clouds, virtualization, operating systems, storage, networks, custom applications, and containers. Deployment can be SaaS or on premises for cloud, hybrid, and on-premises environments. Service desk, orchestration, DevOps, and ServiceNow integrations support incident workflows. Pricing starts at $100 per month, with a 21-day trial and no free plan.

PoWA is a free, self-hosted tool for monitoring and tuning PostgreSQL. It collects and aggregates performance metrics from database instances and presents them in charts. Local mode handles one instance; remote mode gathers metrics from multiple instances into a repository server and can include read-only standbys without restarting PostgreSQL when adding them. The project combines the powa-archivist extension and powa-web interface, with an optional powa-collector daemon for remote deployments. Supported statistics extensions include pg_stat_statements, pg_qualstats, pg_stat_kcache, pg_wait_sampling, and pg_track_settings; pg_stat_statements is mandatory, and the current version targets PostgreSQL 9.4 and newer. HypoPG support enables testing hypothetical indexes without creating real ones. PoWA 5 adds datasource views for replication, background writer, checkpointer, SLRU, WAL, and PostgreSQL 16 or newer I/O statistics, plus per-database snapshots. Metrics can be enabled or disabled, and custom extensions added without modifying PoWA.
