| 15 | # Fixes a process named "proc" by performing the specified action. The |
| 16 | # actions can be check, kill, restart, exist, or fix. The action is specified |
| 17 | # on the command line or is read from a default database, which describes |
| 18 | # the default action to take for each process. The database format and |
| 19 | # the meaning of each action are described below. |
| 20 | # |
| 21 | # database format |
| 22 | # --------------- |
| 23 | # |
| 24 | # name foo required |
| 25 | # cmd /a/b/name args required |
| 26 | # min number optional, defaults to 1 |
| 27 | # max number optional, defaults to 1 |
| 28 | # |
| 29 | # check {null, exist, shell} optional, defaults to exist if not defined |
| 30 | # [shell command shell commands needed only if check=shell |
| 31 | # ... |
| 32 | # shell command |
| 33 | # end_shell] keyword end_shell marks end of shell commands |
| 34 | # fix {kill, restart, shell} required |
| 35 | # [shell command shell commands needed only if fix=shell |
| 36 | # ... |
| 37 | # shell command |
| 38 | # end_shell] keyword end_shell marks end of shell commands |
| 39 | # |
| 40 | # Blank lines and lines beginning with "#" are ignored. |
| 41 | # |
| 42 | # |
| 43 | # Example: |
| 44 | # |
| 45 | # name test1 |
| 46 | # cmd nice /home/kong/z/test1 > /dev/null & |
| 47 | # max 2 |
| 48 | # fix shell |
| 49 | # xterm& |
| 50 | # nice /home/kong/z/test1 > /dev/null & |
| 51 | # end_shell |
| 52 | # |
| 53 | # |
| 54 | # actions |
| 55 | # ------- |
| 56 | # There are 5 possible actions: kill, restart, fix, exist, check. Fix is |
| 57 | # defined to be the kill action, the restart action, or a series of shell |
| 58 | # commands. Check is optionally defined in the database. If check is not |
| 59 | # defined, it defaults to exist. |
| 60 | # |
| 61 | # If the action is specified on the cmd line, it is executed regardless of |
| 62 | # check. The commands executed for each action type is as follow: |
| 63 | # |
| 64 | # switch action: |
| 65 | # kill: |
| 66 | # kill process, wait 5 seconds, kill -9 if still exist |
| 67 | # if still exist |
| 68 | # return "cannot kill" |
| 69 | # else |
| 70 | # return "ok" |
| 71 | # |
| 72 | # restart: |
| 73 | # execute kill |
| 74 | # if kill returned "cannot kill" |
| 75 | # return "cannot kill" |
| 76 | # restart by issuing cmd to shell |
| 77 | # if check defined |
| 78 | # execute check |
| 79 | # if check succeeds |
| 80 | # return "ok" |
| 81 | # else |
| 82 | # return "cannot restart" |
| 83 | # |
| 84 | # fix: |
| 85 | # if fix=kill |
| 86 | # execute kill |
| 87 | # else if fix=restart |
| 88 | # execute restart |
| 89 | # else |
| 90 | # execute shell commands |
| 91 | # execute check |
| 92 | # |
| 93 | # check: |
| 94 | # if check defined as null |
| 95 | # return "fixproc error" |
| 96 | # else |
| 97 | # execute check |
| 98 | # if check succeeds |
| 99 | # return (execute exist) |
| 100 | # return "check failed" |
| 101 | # |
| 102 | # exist: |
| 103 | # if proc exists in ps && (min <= num. of processes <= max) |
| 104 | # return "ok" |
| 105 | # else |
| 106 | # return "check failed" |
| 107 | # |
| 108 | # |
| 109 | # If the action is not specified on the cmd line, the default action is the |
| 110 | # fix action defined in the database. Fix is only executed if check fails: |
| 111 | # |
| 112 | # if fix defined |
| 113 | # if check is not defined as null |
| 114 | # execute check |
| 115 | # if check succeeds |
| 116 | # return "ok" |
| 117 | # execute action defined for fix |
| 118 | # else |
| 119 | # return "fixproc error" |
| 120 | # |
| 121 | # |
| 122 | # If proc is not specified on the command line, return "fixproc error." |
| 123 | # Multiple proc's can be defined on the cmd line. When an error occurs |
| 124 | # when multiple proc's are specified, the first error encountered halts the |
| 125 | # script. |
| 126 | # |
| 127 | # For check shell scripts, any non-zero exit code means the check has failed. |
