The kernel dump (vmcore) generated during system crash provides vital information for post-mortem analysis. Standard tools such as 'crash' provide basic commands to analyze vmcores. But doing a manual review of several thousand similar structures from a dump is very time consuming and in many cases impractical.

PyKdump provides Python based framework which lets you develop programs to quickly extract and process the required information. There are several practical tools already developed on top of PyKdump, e.g. xportshow (TCP/IP info), scsishow (SCSI and LVM), dmshow (multipath), nfsshow (NFS), hanginfo (hang analysis). They quickly extract information from dump and report potential issues. This is extremely useful to developers working on dump analysis.
