5.13 ndb_error_reporter — NDB Error-Reporting Utility

ndb_error_reporter creates an archive from data node and management node log files that can be used to help diagnose bugs or other problems with a cluster. It is highly recommended that you make use of this utility when filing reports of bugs in NDB Cluster.

Options that can be used with ndb_error_reporter are shown in the following table. Additional descriptions follow the table.

ndb_error_reporter did not support the --help option prior to NDB 7.3.3 (Bug #11756666, Bug #48606). The --connection-timeout --dry-scp, and --skip-nodegroup options were also added in this release (Bug #16602002).

Usage

ndb_error_reporter path/to/config-file [username] [options]

This utility is intended for use on a management node host, and requires the path to the management host configuration file (usually named config.ini). Optionally, you can supply the name of a user that is able to access the cluster's data nodes using SSH, to copy the data node log files. ndb_error_reporter then includes all of these files in archive that is created in the same directory in which it is run. The archive is named ndb_error_report_YYYYMMDDhhmmss.tar.bz2, where YYYYMMDDhhmmss is a datetime string.

ndb_error_reporter also accepts the options listed here:

• --connection-timeout=timeout

  Command-Line Format	--connection-timeout=timeout
  Introduced	5.6.14-ndb-7.3.3
  Type	Integer
  Default Value	0

  Wait this many seconds when trying to connect to nodes before timing out.

• --dry-scp

  Command-Line Format	--dry-scp
  Introduced	5.6.14-ndb-7.3.3
  Type	Boolean
  Default Value	TRUE

  Run ndb_error_reporter without using scp from remote hosts. Used for testing only.

• --fs

  Command-Line Format	--fs
  Type	Boolean
