- ppppmmmmnnnnssssaaaadddddddd - add new names to the Performance Co-Pilot PMNS

- $$$$PPPPCCCCPPPP____BBBBIIIINNNNAAAADDDDMMMM____DDDDIIIIRRRR////ppppmmmmnnnnssssaaaadddddddd [----dddd] [----nnnn _n_a_m_e_s_p_a_c_e] _f_i_l_e

- ppppmmmmnnnnssssmmmmeeeerrrrggggeeee(1) performs the same function as ppppmmmmnnnnssssaaaadddddddd and is faster, more
- robust and more flexible. It is therefore recommended that ppppmmmmnnnnssssmmmmeeeerrrrggggeeee(1)
- be used instead.
-
- ppppmmmmnnnnssssaaaadddddddd adds subtree(s) of new names into a Performance Metrics Name
- Space (PMNS), as used by the components of the Performance Co-Pilot
- (PCP).
-
- Normally ppppmmmmnnnnssssaaaadddddddd operates on the default Performance Metrics Namespace
- (PMNS), however if the ----nnnn option is specified an alternative namespace is
- used from the file _n_a_m_e_s_p_a_c_e.
-
- The default PMNS is found in the file $_P_C_P__V_A_R__D_I_R/_p_m_n_s/_r_o_o_t unless the
- environment variable PPPPMMMMNNNNSSSS____DDDDEEEEFFFFAAAAUUUULLLLTTTT is set, in which case the value is
- assumed to be the pathname to the file containing the default PMNS.
-
- The new names are specified in the _f_i_l_e, arguments and conform to the
- syntax for PMNS specifications, see ppppmmmmnnnnssss(4). There is one PMNS subtree
- in each _f_i_l_e, and the base PMNS pathname to the inserted subtree is
- identified by the first group named in each _f_i_l_e, e.g. if the
- specifications begin
-
- myagent.foo.stuff {
- mumble 123:45:1
- fumble 123:45:2
- }
- then the new names will be added into the PMNS at the non-leaf position
- identified by myagent.foo.stuff, and following all other names with the
- prefix myagent.foo.
-
- The new names must be contained within a single subtree of the namespace.
- If disjoint subtrees need to be added, these must be packaged into
- separate files and ppppmmmmnnnnssssaaaadddddddd used on each, one at a time.
-
- All of the files defining the PMNS must be located within the directory
- that contains the root of the PMNS, this would typically be
- $$$$PPPPCCCCPPPP____VVVVAAAARRRR____DDDDIIIIRRRR////ppppmmmmnnnnssss for the default PMNS, and this would typically imply
- running ppppmmmmnnnnssssaaaadddddddd as root.
-
- Provided some initial integrity checks are satisfied, ppppmmmmnnnnssssaaaadddddddd will update
- the PMNS using ppppmmmmnnnnssssmmmmeeeerrrrggggeeee(1) - if this fails for any reason, the original
- namespace remains unchanged.

-
-
-
- The ----dddd option allows the resultant PMNS to optionally contain duplicate
- PMIDs with different names in the PMNS. By default this condition is
- considered an error.
-
- CCCCAAAAVVVVEEEEAAAATTTT
- Once the writing of the new _n_a_m_e_s_p_a_c_e file has begun, the signals SIGINT,
- SIGHUP and SIGTERM will be ignored to protect the integrity of the new
- files.

- PPPPMMMMNNNNSSSS____DDDDEEEEFFFFAAAAUUUULLLLTTTT is unset
-
- PPPPCCCCPPPP EEEENNNNVVVVIIIIRRRROOOONNNNMMMMEEEENNNNTTTT
- Environment variables with the prefix PPPPCCCCPPPP____ are used to parameterize the
- file and directory names used by PCP. On each installation, the file
- /_e_t_c/_p_c_p._c_o_n_f contains the local values for these variables. The
- $$$$PPPPCCCCPPPP____CCCCOOOONNNNFFFF variable may be used to specify an alternative configuration
- file, as described in ppppccccpppp....ccccoooonnnnffff(4).
