sssd-systemtap 5 File Formats and Conventions sssd-systemtap SSSD systemtap information This manual page provides information about the systemtap functionality in sssd 8 . SystemTap Probe points have been added into various locations in SSSD code to assist in troubleshooting and analyzing performance related issues. Sample SystemTap scripts are provided in /usr/share/sssd/systemtap/ Probes and miscellaneous functions are defined in /usr/share/systemtap/tapset/sssd.stp and /usr/share/systemtap/tapset/sssd_functions.stp respectively. The information below lists the probe points and arguments available in the following format: probe $name Description of probe point variable1:datatype variable2:datatype variable3:datatype ... probe sssd_transaction_start Start of a sysdb transaction, probes the sysdb_transaction_start() function. nesting:integer probestr:string probe sssd_transaction_cancel Cancellation of a sysdb transaction, probes the sysdb_transaction_cancel() function. nesting:integer probestr:string probe sssd_transaction_commit_before Probes the sysdb_transaction_commit_before() function. nesting:integer probestr:string probe sssd_transaction_commit_after Probes the sysdb_transaction_commit_after() function. nesting:integer probestr:string probe sdap_search_send Probes the sdap_get_generic_ext_send() function. base:string scope:integer filter:string attrs:string probestr:string probe sdap_search_recv Probes the sdap_get_generic_ext_recv() function. base:string scope:integer filter:string probestr:string probe sdap_parse_entry Probes the sdap_parse_entry() function. It is called repeatedly with every received attribute. attr:string value:string probe sdap_parse_entry_done Probes the sdap_parse_entry() function. It is called when parsing of received object is finished. probe sdap_deref_send Probes the sdap_deref_search_send() function. base_dn:string deref_attr:string probestr:string probe sdap_deref_recv Probes the sdap_deref_search_recv() function. base:string scope:integer filter:string probestr:string probe sdap_acct_req_send Probes the sdap_acct_req_send() function. entry_type:int filter_type:int filter_value:string extra_value:string probe sdap_acct_req_recv Probes the sdap_acct_req_recv() function. entry_type:int filter_type:int filter_value:string extra_value:string probe sdap_search_user_send Probes the sdap_search_user_send() function. filter:string probe sdap_search_user_recv Probes the sdap_search_user_recv() function. filter:string probe sdap_search_user_save_begin Probes the sdap_search_user_save_begin() function. filter:string probe sdap_search_user_save_end Probes the sdap_search_user_save_end() function. filter:string probe dp_req_send A Data Provider request is submitted. dp_req_domain:string dp_req_name:string dp_req_target:int dp_req_method:int probe dp_req_done A Data Provider request is completed. dp_req_name:string dp_req_target:int dp_req_method:int dp_ret:int dp_errorstr:string The information below lists the probe points and arguments available in the following format: function acct_req_desc(entry_type) Convert entry_type to string and return string function sssd_acct_req_probestr(fc_name, entry_type, filter_type, filter_value, extra_value) Create probe string based on filter type function dp_target_str(target) Convert target to string and return string function dp_method_str(target) Convert method to string and return string Start the SystemTap script (stap /usr/share/sssd/systemtap/<script_name>.stp), then perform an identity operation and the script will collect information from probes. Provided SystemTap scripts are: dp_request.stp Monitoring of data provider request performance. id_perf.stp Monitoring of id command performance. ldap_perf.stp Monitoring of LDAP queries. nested_group_perf.stp Performance of nested groups resolving.
