Highlights

-
Next-level observability platform
Obcerv answers the complex data monitoring needs of today's modern IT operations. As an observability platform for data storage and analytics, Obcerv efficiently manages the volume, variety, and velocity of data from different sources. It is your one-stop shop for storing, accessing, and analysing critical monitoring data. -
Flexibility for lower storage costs
Obcerv collects data from multiple feeds and streams while giving you the ability to define rules and organise entities for targeted monitoring. Through meta-tagging, dimensionality is provided to stored data. Data compression lowers storage costs while ensuring that data fidelity is maintained. -
Contextualized and rationalised alerts
Obcerv correlates data and consolidates alerts from various monitoring tools. Obcerv brings context and meaning to alerts coming from multiple platforms. See Alerting. -
Centralized dashboarding
Data from multiple monitoring sources are visualised in easy to create and shareable native and Grafana dashboards. Obcerv’s forecasting algorithms can also predict business levels right on dashboards. See Obcerv Dashboards and Grafana app. -
Streamlined log investigation
Obcerv can store large amounts of log data for deeper root cause analysis. It is easier to find related log errors while having the convenience to view logs side-by-side or in-line. See Logs. -
Interoperability through scalable APIs
Scalable APIs make Obcerv fully interoperable with a range of applications, ensuring that Obcerv seamlessly works with ITRS and non-ITRS products alike. See API Gateway. -
