master is a development branch. Please download release tar balls in https://github.com/ovis-hpc/ovis/releases, or check out OVIS-4 branch for the pre-release instead.

OVIS is a modular system for HPC data collection, transport, storage, log message exploration, and visualization as well as analysis.

LDMS is a low-overhead, low-latency framework for collecting, transfering, and storing metric data on a large distributed computer system. The framework includes

• a public API with a reference implementation,
• tools for collecting, aggregating, transporting, and storing metric values,
• collectors for several common types of metrics.
• Data transport over socket, RDMA (IB/iWarp/RoCE), and Cray Gemini as well as Aries.

The API provides a way for vendors to expose system information in a uniform manner without being required to provide source code for accessing the information (although we advise it be included) which might reveal proprietary methods or information.

Metric information can be updated by a kernel module which runs only when applications yield the processor and transported using RDMA-like operations, resulting in minimal jitter during collection. LDMS has been run on 10,000 cores collecting over 100,000 metric values per second with less than 0.2% overhead.

See LDMS for more details about LDMS project.

SOS is a high-performance, indexed, object-oriented database designed to efficiently manage structured data on persistent media. More information can be found at the SOS GitHub website https://github.com/opengridcomputing/SOS.

Baler is an aggregation of log message exploration and analysis tools. balerd is the tool that tokenizes log messages using user-specified dictionaries. The log messages are then groupped together according to their token sequences. Each group is represented by a Baler pattern -- a token sequence.

Baler stores the log message patterns, the raw log messages, and other infomation in its database. bquery is a tool to query Baler database for the Baler patterns, raw log messages, and message statistics by hosts and/or time.

Baler also comes with an association mining tool -- bassoc -- that can be used to discover sequence of occurrence patterns of log messages and to perform causal analysis.

Baler repository can be found at https://github.com/opengridcomputing/baler.

You may clone OVIS source (and its submodules) from the official Git repository:

git clone https://github.com/ovis-hpc/ovis.git
