Overview
DBcollect is a tool that collects database and host information from Oracle database servers in a standardized way, so it can easily be processed by workload analysis tools. It supports Enterprise Linux (RHEL, OEL, CentOS) as well as AIX and Solaris (SPARC).
Why DBcollect
In the past, I frequently got workload data from customers in all kinds of strange formats (unusable AWR formats, reports in text format, with far too large AWR intervals, etc). Unix info was usually either not available at all or a random dump of output of some commands. By standardizing the reporting in a single tool, we get consistent, reliable database and host information.
This is needed for creating workload assessments where the data must be machine readable in a standardized format.
In most cases it automatically detects all running Oracle instances on the host.
Collected data
- Host CPU, memory, network interface and disk info
- Running processes, file systems, installed packages, os version and release etc.
- Hardware vendor, product etc where possible
- SAR reports
- AWR or Statspack reports for the given period (default 10 days)
- Additional database information (such as capacity of tablespaces and disks, settings, compression analysis, backup, ...)
Safety
DBcollect is designed to run on production systems and great effort has been spent on making it robust. The SECURITY section on the github page explains in great detail how this works. Note that dbcollect has an option to remove SQL code from AWR reports, in case this is condidered a security or confidentiality issue.
