debug: print out debugging information about the handler chain being called.(3)

NAME
debug: print out debugging information about the handler chain being called. - This is a useful module for run-time debugging of requests as the pass this handler in a calling chain.

  handler
void netsnmp_init_serialize (void)
initializes the serialize helper which then registers a serialize handler as a run-time injectable handler for configuration file use.
void netsnmp_init_read_only_helper (void)
initializes the read_only helper which then registers a read_only handler as a run-time injectable handler for configuration file use.
void netsnmp_init_bulk_to_next_helper (void)
initializes the bulk_to_next helper which then registers a bulk_to_next handler as a run-time injectable handler for configuration file use.
void netsnmp_init_table_dataset (void)
void netsnmp_init_stash_cache_helper (void)
initializes the stash_cache helper which then registers a stash_cache handler as a run-time injectable handler for configuration file use.
void netsnmp_init_helpers (void)
call the initialization sequence for all handlers with init_ routines.

  Functions
netsnmp_mib_handler * netsnmp_get_debug_handler (void)
returns a debug handler that can be injected into a given handler chain.
void debug_print_requests (netsnmp_request_info *requests)
int netsnmp_debug_helper (netsnmp_mib_handler *handler, netsnmp_handler_registration *reginfo, netsnmp_agent_request_info *reqinfo, netsnmp_request_info *requests)
void netsnmp_init_debug_helper (void)
initializes the debug helper which then registers a debug handler as a run-time injectable handler for configuration file use.

Detailed Description

This is a useful module for run-time debugging of requests as the pass this handler in a calling chain. All debugging output is done via the standard debugging routines with a token name of 'helper:debug', so use the -Dhelper:debug command line flag to see the output when running the snmpd demon. It's not recommended you compile this into a handler chain during compile time, but instead use the 'injectHandler' token in the snmpd.conf file (or similar) to add it to the chain later:

injectHandler debug my_module_name

to see an example output, try:

injectHandler debug mibII/system

and then run snmpwalk on the 'system' group.
