NAME

SYNOPSIS

9       persist-tool [command] [options]
10

DESCRIPTION

12       NOTE: The persist-tool application is distributed with the syslog-ng
13       system logging application, and is usually part of the syslog-ng
14       package. The latest version of the syslog-ng application is available
15       at the official syslog-ng website[1].
16
17       This manual page is only an abstract, for the complete documentation of
18       syslog-ng, see the The syslog-ng Administrator Guide[2].
19
20       The persist-tool application is a utility that can be used to dump the
21       content of the persist file, and manipulate its content.
22
23           Warning
24           Persist-tool is a special tool for syslog-ng experts. Do use the
25           tool unless you know exactly what you are doing. Misconfiguring it
26           will result in irrecoverable damage to the persist file, without
27           any warning.
28
29           Note
30           Limitations:
31
32           •   The persist-state functions can be used only with syslog-ng PE
33               5 LTS style persist file (SLP4). Older persist files are not
34               supported.
35
36           •   Wildcard characters are not supported in file/directory names.
37

THE DUMP COMMAND

39       dump [options] [persist_file]
40
41       Use the dump command to print the current content of the persist file
42       in JSON format to the console.
43
44       The dump command has the following options:
45
46       --help or -?
47           Display a brief help message.
48
49       Example:
50
51           persist-tool dump /usr/local/var/syslog-ng.persist
52
53       The output looks like:
54
55           run_id = { "value": "00 00 00 00 0C 00 00 00 " }
56           host_id = { "value": "00 00 00 00 5F 49 2F 01 " }
57

THE ADD COMMAND

59       add [options] [input_file]
60
61       Use the add command to add or modify a specified state-entry in the
62       persist file. The state-entry should be in the same format as the dump
63       command displays it. If the given state-entry already exists, it will
64       be updated. Otherwise, a new value will be added. If the given persist
65       state is invalid, it will be skipped.
66
67       To use the add command: use persist-tool dump to print the content of
68       the current persist file, and redirect it to a file. Edit the content
69       of this file. Use persist-tool add with this file to modify the
70       persist.
71
72       The add command has the following options:
73
74       --help or -?
75           Display a brief help message.
76
77       --output-dir=<directory> or -o
78           Required parameter. The directory where the persist file is located
79           at. The name of the persist file stored in this directory must be
80           syslog-ng.persist.
81
82       Example:
83
84           /usr/local/bin/persist-tool add dump_persist -o .
85
86       The valid output looks like:
87
88           log_reader_curpos(Application)      OK
89           affile_sd_curpos(/var/aaa.txt)        OK
90
91       The invalid output looks like:
92
93           log_reader_curpos(Application)      OK
94           wrong
95                   FAILED (error: Invalid entry syntax)
96           affile_sd_curpos(/var/aaa.txt)        OK
