1 24-OCT-2010: Torrus release 1.0.9
3 It is recommended to re-run discovery and compilation immediately after
8 -- WebUI handling is re-designed. FastCGI is supported with Apache
9 and Lighttpd. User authorization option has changed its name:
10 "$Torrus::CGI::authorizeUsers". Login page has now "remember me" checkbox.
11 Apache configuration statements for mod_perl have slightly changed.
12 Removed dependency: libapreq2 is no longer needed.
14 -- New Perl module required by installer: JSON
16 -- New discovery modules: Force10, NetBotz, Arista, ALU_Timetra, Foundry,
19 -- Support for semi-transparent lines and areas in multigraphs.
21 -- Support for arbitrary names for subtrees and leaves (node-display-name
22 parameter). Now original interface names are displayed, without underscores.
24 -- Monitor alarms are now preserved between config re-compilations. Also
25 dynamic tokenset members are preserved. A new utility:
26 "torrus flushmonitors" flushes old alarms.
28 -- New parameter: nodeid. It is designed for easier integration of Torrus with
29 other OSS systems. See the "NodeID usage guidelines" document for more
32 -- Current SNMP failures are recorded in a database and displayed by
33 "torrus snmpfailures" utility. The output is in JSON format, so it's easy
34 to integrate into other alerting systems.
36 -- RHEL compatibility: the old Init script did not stop the daemons properly
39 -- Compatibility with the newest version of Net::SNMP module.
41 -- Host-based authentication: remote systems, such as customer self-care
42 portals, can retrieve graphs from Torrus WebUI.
44 -- Performance optimizations: XML compiler runs 10-15% faster.
46 -- Custom CSS styles must no longer reside in Torrus installation directory.
51 26-APR-2010: Torrus release 1.0.8bf01
53 Bugfix release. No new features or functionality.
55 05-APR-2009: Torrus release 1.0.8
57 Note: a complete re-compile of the XML is required after upgrading.
61 -- BerkeleyDB stability has significantly improved due to new signal handlers.
63 -- View parameters can be overridden with URL variables "Gstart",
66 -- Collector initialization time is improved by shifting some work
69 -- New command-line utility: srvderive. It combines several serviceIDs into
70 a single report by calculating their sum or maximum value
71 (sponsored by nexellent ag, www.nexellent.ch)
73 -- A number of bugfixes and minor imprvements.
75 -- Added SNMP discovery support for Arbor E series and Liebert HVAC
78 05-AUG-2008: Torrus release 1.0.7
82 -- Added and improved vendor support for Symmetricom, Juniper JunOS,
85 -- New discovery parameters, selectors and selector actions.
87 -- Default value for "collector-timeoffset-step" increased from 30 to 60
88 seconds. 30 seconds is too short for many installations.
90 -- Support for PostgreSQL in reports generator.
92 -- Support for IPv6 in SNMP discovery and collector.
94 -- New collector plugin: "tp-rawexport" for plaintext export of collector data.
96 -- Cisco QoS monitoring plugin "tp-cisco-cbqos" upgraded to version 1.6.
97 It fixes an old bug in RRD file naming, thus all the QoS-related RRD files
98 would have to be renamed or started from scratch.
100 -- Other minor enhancements and bugfixes (see ChangeLog for details).
103 03-AUG-2007: Torrus release 1.0.6
107 -- All the trees need to be recompiled after Torrus upgrade.
109 -- Search capability. The nodes can be searched within a tree or globally.
110 The search database needs to be updated with "torrus buildsearchdb"
113 -- GUI improvements. Recursive view is restricted and is not offered
114 averywhere. Bugfix for Mozilla browser compatibility: now the graph
115 images are clickable.
117 -- devdiscover accepts multiple DDX files. Combined with multithreading,
118 this improves the discovery performance even further.
120 -- SNMP collector periodically refreshes the table mappings. This helps
121 for modular routers with online insertion and removal: the collector
122 does not need to be restarted after the physical configuration changes.
123 Also the OIDs that return noSuchObject are excluded from polling
126 -- New MIBs support: Cisco SCE per-service traffic statistics; Cisco CAR
127 statistics; Cisco Ethernet MAC accounting statistics now available on
128 subinterfaces; JunOS per-CoS stats; support for Alteon hardware.
130 -- <filepattern> XML statement is no longer supported. Use the rrddir2xml
133 -- The CDEF collector from Chrstian Schnidrig is integrated in the main
134 distribution. Devdiscover supports traffic summaries for multiple
137 -- The report generator can generate HTML in any tree. Earlier it was
138 generating the reports only for the trees where data was collected.
139 This improvement allows to split the collecting and viewing trees.
141 -- The installer allows multithreading for Perl version 5.8.8 or higher only.
142 Earlier versions are known for memory leaks in multithreaded operation.
144 -- Multiple collector instances per tree. This improves the CPU utilization
145 for multi-CPU servers. See the torrus_collector manpage.
149 25-JAN-2007: Torrus release 1.0.5
151 This is a major release with many new features.
155 -- Bugfixes in SNMPv3 support
157 -- Perl multithreading. If threads are supported by local Perl,
158 Devdiscover can perform parallel discoveries per output file.
159 Also the Collector runs a background thread for RRD updates.
161 -- Improvement in SNMP collector initialization. Now the collector expands
162 the interface names and other maps asynchronously, which dramatically
163 reduces the initialization time for large installations.
164 Cisco QoS plugin needs an upgrade to version 1.4 or higher.
166 -- New vendor support in SNMP discovery engine:
167 Motorola BSR CMTS (ex-Riverdelta), Cisco SCE, BGP prefix statistics for
168 Cisco IOS routers, Cisco IOS XR support.
170 -- DOCSIS upstream statistics have changed the format, therefore
171 the old stats will be lost after upgrade. The stats now include the
174 -- Interface statistics now contain "All Errors" tab with all error graphs
177 -- Interface traffic graphs may contain bandwidth utilization percentage
178 information (see RFC2863_IF_MIB::bandwidth-usage in SNMP Discovery
181 -- Cisco MAC accounting can also be used for billing reports.
184 20-JUL-2006: Torrus release 1.0.4
186 This is a major release with many new features.
190 -- SNMP Version 3 support in Devdiscover and SNMP collector.
192 -- Usage reports for billing. Including 95% percentile reports.
193 More details at http://torrus.org/reporting_setup.pod.html
195 -- Various improvements in SNMP discovery engine and new equipment
198 -- Improved monitor notifications. New parameter: "severity"
199 and new action "action_notify".
201 -- New torrus-siteconfig.pl variables to improve WebUI customization
205 02-AUG-2005: Torrus release 1.0.3
207 This is a minor bugfix release. Unreachable device handling is improved, and
208 also there's a possibility to specify extra Perl library path in ./configure
211 27-JUL-2005: Torrus release 1.0.2
213 The new release requires one additional Perl module to be
214 installed: Date::Parse. You can install it from CPAN by using the command:
215 perl -MCPAN -e 'install Date::Parse'
219 -- Unreachable SNMP devices handling has significantly improved.
220 The default unreachable timeout is set to 6 hours.
222 -- Support for the new mod_perl 2.0 layout.
224 -- New OID in TORRUS-MIB: torrusMonitorDesc, for easier processing of
227 -- ./configure checks if the user "torrus" exists in the system
229 -- New SNMP discovery parameters:
230 RFC2863_IF_MIB::only-interfaces
231 disable-snmpcollector
233 -- On the graph page, it is now possible to choose the date for displaying
236 -- The Cisco CPUs are now managed by devdiscover's selectors.
237 This allows you to add monitors to specific CPU graphs, and also add them
241 21-JUN-2005: Torrus release 1.0.1
245 -- SNMP errors are now handled better. See the User guide for more details.
247 -- New command line option for monitor: --delay. The init script
248 launches the monitor with 20 minutes delay, to allow the collector
249 update RRD files before monitoring them.
251 -- New devdiscover option: --fallback. It is useful in large production
252 environments when it's important to have a device in the web interface
253 even if it's turned off
255 -- Cisco DOCSIS templates now include Total, Active, and Registered
256 modem quantities. RRD file structure has changed, so the graphs will
259 -- The meaning of $Torrus::Renderer::stylingProfileOverlay
260 has changed: now it refers to a file name.
263 10-JUN-2005: Torrus release 1.0.0
265 In this release, compared to RRFW release 0.1.8:
267 -- New directory structure, with local configuration completely separated
268 from the distribution files
270 -- Comand-line wrapper "torrus" for executing all commands, with short aliases
271 ("dd" for "devdiscover" etc.)
