ZABBIX 1.1:

> -Should the update linkage buttons synchronize the stuff between the host and
 his templates....... this is very usefull?
 -Did you know what is very very very bad..... not having a add triggers and
 graphs from this host button.... like the one that adds items.
 -Can u make possible to change the simple graph..... like changing it to
 bold....
 - anvanced SNMP trapper
 - add acknowledgements

 - add HTML block to the screen cell (to see external data, images, etc)
 - centralised agent upgrade
 - take advantage of 'make dist'

TKOM:

 - alarms forwarding to external systems (using SNMP traps, for example)
 - alarm/trigger sounds
 - SNMP trap processing
 - SNMP trap sending

 - clickable map in map configuration
 - rus/lat characters for graphs
<?
print_r($_POST);
?>
<form method="POST" action="">
<input type="image" src="images/image.jpg" name="imgname">
</form>

4. SNMP traps. Make possible action definition for the SNMP trap-related
 events.

7. snmp traps kak?

dalee pozhelanija:

OTHER:

 - multi-institution support

 - improve removal of item related data from history
'-' doesn't work in trigger expressions (a-b=0)

 When editing trigger actions in subject it says something
for instance "low disk space on {HOSTNAME}'s /usr"
when submitting form, it dumps mysql error, due to non-
escaped single quote. I believe all user input should be
escaped before submitting to mysql.

 - negative values in graphs
 - check all screens if they are user friendly and present information in the best possible way
 - possibility (a button) to recheck unsupported parameters
 - add advanced task scheduler/executor to ZABBIX
 - agent incorrectly returns amount of free/available memory on HP-UX (must be 24GB)

 - add icons to a map by clicking mouse
 - optionally support map generation in JPEG. PNG images are huge!
 - security-related issues

There are still quite a few strcpy calls made against non-const user, database, or remote supplied data, in both the src/* and include/* directories.

printf calls w/o static format specifiers...
in src and include:
grep -R printf * | grep -v "\%\|Makefile\|Binary"

extensive use of atoi rather than something w/ bounds checking like strtol.

Most of the signal handlers all need to delay or block signals to avoid signal race conditions, as they call non-reentrant functions.

 - in user administration, add many resources from a list (not by one ID)
 - availability report for day/week/month/etc
 - check if items delay works
 - review PHP code for simplifying (urls, iif() )
 - fix screenedit.php permissions

 Kak naschet dopolnenij k time & date:
 * tipa month, day, year, hour, minute, ...

 Nu i k 'str' dodlstj csjakie vsjakosti tipa
 * substr, length, poisk pozicii simvola/podstroki (FIND/SEARCH v Excel),
 podscet kolichestva simvola (tipa skoljko tam zapjatih)...

 - add requirement for fping to the manual
 - separate login.php and index.php
 - remove icmpping and others from the QUEUE

 - summarising report about triggers/actions/items. Show items without triggers,
trigger wihout actions, etc etc
 5) When adding trigger, next page is without triggers of this host. Is  
 it possible after adding triger to go back to triggers of this host page ?

 - zabbix thinks that host is unrechable if it receives string for numeric item

 - think about implementation of sinchronised items like cpu[usr], cpu[sys], cpu[idle]

 - implement complex SLA calculation (donwtimes, working/non-working hours), etc. See
forum Open Discussion for more info.
 - add selection of MIN/MAX/AVG for graphs
 - rewrite validation and evaluation of expressions (i.e. make >-1 work)
 - support for 'Clone' (graphs and screens)
 - add support of interface statistics under Solaris and FreeBSD
 - calculate MIN value for graphs (do not use '0')
 - infrastructure for reports
 - stacked graphs

 - check if alert and service alert is added after host become reachable again

LATER:

 - add zabbix[unixtime] and lastupdate() and tick() to get rid of nodata()
 - check return code for alert scripts
 - zabbix_agentd to support processor load, swap[*] and memory[*] onder AIX
 - make session expiration time configurable in config.php
 - mess with user groups when running under root
 - support for PREFIX/zabbix/etc (configuration files)
 - trapper item. Source->Alarms do not grow when last status is unknown for
latest trigger (item type  = TRAPPER)
 - SNMP traps. Condition to switch expression off. New function which would return
 status of the trigger could help. 

 - when zabbix cannot evaluate expression it does not change status to UNKNOWN but adds ALARM (UNKNOWN) 
 - preset time for graphs

 - links to Zabbix frontend in alert emails
 - strings items for graphs
 - ability to add a library of  userwritten c-functions with dlopen/dlsym to
the agent with a predefined API that can return values to suckerd (for both 
suckerd and agentd)
 - zabbix_trapperd does not start if PostgreSQL and DBConnectOnEach=1

 - [10] Refresh stop ability. At least for graphs and triggers being selected.
 - [10] IT Services. Show downtimes for weeks.
 - [10] IT Services. User view, show algorithm.
 - [10] BUG. When adding new service, service name is wrong.
 - [10] IT Services. SLA for a period of time only (09:00-18:00)

LS:

 - update trigger value immediately after add or update
 - graphs. Dobavljatj item so smescheniem vo vremeni
 - check permissions for zabbix_agentd when started under root
 - add item to group (not to all)
 - update host from template

change(N) - raznica mezhdu poslednim i na N vremeni ranee poluchennim
znacheniem;
abschange(N) = abs(change(N));

trend(N) - linejnaja aproksimacija sled.znachenija po interval vremeni N;

nu i massu matematicheskih mozhno - dlja super-advanced chuvakov:

 - if 'Update', then default action (button 'Enter') must be Update
 - do not check SNMP port existance if Item is not SNMP
 - add item to host group
 - add descriptions to items
 - link host (group) to template

graphs:

 - min value (0 or automatic)
 - customisation of font size
 - link items to show them in one graph (network in/out) 

 - snmp oid symbolic representation
 - periodically check unsupported items (NxInterval). Can be configurable.
 - Latest values->Host->[Show not monitored]

HP:

 - add threshold,min,max line for user-defined graphs
 -

 - [3] Windows event log checking.
 - [4] Latest values. Link to page which shows list of all triggers-related
 to the item.
 - [4] users.php. Link to page which shows all actions defined for this user.
 - [5] Configuration of items/triggers. Add Select.
 - [7] SLA algorithm (A - 0%, B - 100% -> availability of AB = 50%)
 - [7] IT Service % must start at 01.01.20xx, not first day of the week
 - [7] ALARMS. Ability to select events by specifying date from/to.
 - [9] History of who and when changed trigger comment. As starting point: who and when
 did latest changes.
 - [9] ... the history to be used to see who did changes and who wrote specific parts
 of comments to know who is in charge for the instructions
 - [9] ... find outdated instructions to initiate its renewal (review)

LS:

 - detailed description for items

TOP PRIORITY:

 - fix update of 'status'. When added it never gets updated, if server is already unreachable.
 - add more checks for forms (check all possible wrong values)
 - support of fetch_html[*]
 - zabbix_agentd to support swap[*] and memory[*] onder AIX

BUGS:

 - add protection from IT Service looping

DIFFERENT TASKS:

 - SNMP trapping
 - distributed monitoring
 - personalisation (refresh rate, graph size, default graph period, etc)
 - SNMP-walk in WEB interface
 - add UserParameter without restart of an agent

TODO:

- Agent
 1. An API so that I can build and active agent into
    the centralized monitoring point of my application.
 2. max/min/average values during the poll pause along with last value to catch
CPU spikes otherwise invisible (have had these problems with BMC Patrol).
 3. Ability to add a library of  userwritten c-functions with dlopen/dlsym to
the agent with a predefined API that can return values to suckerd.

Not ready yet:

1. Monitoring of Windows (2000) services via SNMP
This is an extension I wrote based on your SNMP checker that scans through the Windows SNMP mib to check if a specified
+process is running. I thought it may be able to be used in a similar situation to the new SIMPLE check.

2. Basic schedule to monitor certain items during specified period.
I made changes to the PHP frontend and zabbix_sucker.c to enable the user to specify a time period (like between 9am-5pm) when
+the item should be checked.
(From: "Dave McCrudden" <dmccrudden@custcare.com.au>)


 - do not send notifications at certain periods of time. Do not monitor services at certain periods of time.
 - decrease number of TCP connections between server and agent
 - add triggers for all hosts at once
 - check new Mariusz patches
 - add support for downtimes, user availablity, etc

HB:

 - BUG. history graph goes left
 - personalisation (refresh rate, graph size, default graph period, etc)

 - LDAP authorisation (should work with MSWindows LDAP)

WIN32 Agent:

* API for sub-agents
* Support for check_port[] parameter
* Support for check_service[] parameter
* Installation program
* Possibility to store configuration in registry
* Configuration tool (may be through MMC?)

 OTHER:

 - support for netload under other platforms
 - make kstat structure local (instead of static)
 - collect network and other statistics using kstat()
 - apply Mariusz's patches
 - support for complex reports
 - support for check_service[samba]
 - ability to execute command on server monitored
 - support for OS X (network loads, disk loads)
 - check for function parameters in evaluate_simple_expression
 - update trigger status to UNKNOWN if cannot evaluate function 

 LATER:

 - setup demo site
 - different sound files for different severity
 - think about service node types (some nodes will automatically register
  problem)
