Question re: Using the log[*] Key

zab_monkey — Thu, 09 Sep 2010 04:27:12 GMT

Hello all,

I have set up an item, that uses the Active Check log[,...]

The Key looks thus:

log[/tmp/syslog.log,Notification]

I have a Trigger set up, looking for the regexp 'Notification' and it all works great, except for one bit.

Upon reading the manual, the explanation about 'log' says that it will use 2 things from the DB to determine whether it has read the most recent iteration of the file or not, 1 being the file size (lastlogsize) and the second being a time stamp (lastclock).

Basically, what I am getting is every iteration within the file being reported on, not just the last. The manual seems to imply this shouldn't be the case.

For instance, the syslog may have a line item that reads:

# Notification : LINE 1

Then, the trigger will activate and I will get an alert, with all the detail, which is great. However, if another notification occurs in the log file, for example.

# Notification : LINE 1
# Everything is ok
# Notification : LINE 3

It will record, in its history, both lines, the new one AND the old one again. So I get 2 email notifications since it has found 2 again.

I checked the DB and can confirm that the 'lastclock' AND 'lastlogsize' do update as they should, but it still alerts me to every iteration in the log file every time a new one is found. (So you can imagine, if I have 60 Notifications, I don't want to get 60 alerts all over again when its finds another one. And I don't want to fill up the history records with ones I already know about)

So, the questions are:

1. Do I have something missing from my KEY to say that it should only look for new iterations since last check?
2. Is there some other caveat I have forgotten to include?

Any direction would be greatly appreciated.

Regards,

JC

p.s Current version is 1.8.3 for both server and agent, that's probably important :)

Can't access the webinterface anymore

D07. — Wed, 08 Sep 2010 18:33:24 GMT

Hi,

In my internship I got the assignment to inspect network monitoring tools, choose the best and make it work. I have choosen Zabbix and I believe its the right decission but my lack of skill with Linux is threathening my internship.

I had a Zabbix running with some items (external ping script) and triggers configured. Data was coming in, nice. But the dates where off 2 hours. Googled a bit and changed the date.timezone to date.timezone = Europe/Brussels in /etc/php5/apache2/php.ini. At weblogin I get a message that i propably had miswritten smt. Tried date.timezone = Europe/Amsterdam. This appeared to work for a while.

Next day i turn my pc (64 bit quad core) back on and time was wrong on the server. Also time in webserver was wrong and bigger problem, different from servertime. When i synchronized time to ntp server, time was off by two hours. At this point I removed ntp making my mentor fell of his chair (sort of speaking).

I know he is right, I agree that its not done but none the less I was happy to see that my clock remained stable.

By this time somewhere along the road I find myself totally not capable of accessing the webinterface. In the /var/log/apache2/error.log I find message with: exit signal Segmentation fault (11). I think something is going wrong with php or/and Apache but I dont know what or how.

If anyone can shine some light it would very much appreciated.

Greetings

BUG: When using Auto-Login - URL After Login doesn't work 1.8.3

Axilla — Wed, 08 Sep 2010 15:30:58 GMT

Documentation on value format for 'Log' type item

whisky — Wed, 08 Sep 2010 15:29:47 GMT

when using zabbix_sender key/value protocol
do someone know how to format the value for 'Log' item type ?

as the log items have local_time, source, severity, eventid and value
properties.

this is not documented

(Guess I'm going to look the source ;-))

Change graphs from K to Whole Numbers

Axilla — Wed, 08 Sep 2010 15:12:28 GMT

How do I change this? I can't find anywhere to make Zabbix display whole numbers. I didn't specify a unit of measure so why is it defaulting to a unit of measure?

Автоматическое добавление "Группа узло

Surgutor — Wed, 08 Sep 2010 14:49:42 GMT

Добрый день.
Кто-нибудь ковырялся в структуре БД?
Мне необходимо с помощью sql-инъекций автоматически вносить информацию в БД Zabbix. SQL-инъекции будут отправляться WEB-интерфесом, который я же и создал + скрипты на shell.
Например. Есть физический сервер VZ1-Server, на котором работают несколько VPS-машин.
VZ1-Server будет являться "Группа узлов связи", а VPS-машины "узлами связи".
Пока я понял, чтобы добавить новую "Группу узлов связи", необходимо в таблицу
zabbix.groups ввести инъекцию:

Code:

INSERT INTO zabbix.groups (name, internal) VALUES ('VZ1-Server','0');

Правда, я не понял, как они соблюдают уникальность groupid, поэтому я в своей таблице поставил флажок auto_increment.

Добавление нового "узла связи" в лице новой VPS-машины происходит с помощью sql-инъекции в таблицу zabbix.hosts:

Code:

INSERT INTO zabbix.hosts (host, useip, ip) VALUES ('VPS-1','1','192.168.0.1');

Остальные поля заполняются по умолчанию. Правда тут опять же не понятно, как они соблюдают уникальность hostid, поэтому опять же поставил auto_increment.

Даже понял, как прявязать шаблон к VPS-машинам. Для этого служит таблица zabbix.hosts_templates, где ставится соответствие hostid -> templateid. При этом оба параметра являются hostid в таблице zabbix.hosts, то есть "узлы связи" и "шаблоны" хранятся в одной таблице zabbix.hosts.

Теперь вопросы:
#1 То, что я ставлю auto_increment никак не влияет насаму таблицу? В последующих обновлениях не будут проблемы?
#2 Как мне привязать "шаблон" к "группе узлов связи"? Чтобы шаблон принадлежал не "группе узлов связи" Templates, а "группе узлов связи" VZ1-Server, которую я сам же и создаю
#2 Как мне привязать "узлы связи", которые я создаю, "группе узлов связи" VZ1-Server, которую я сам же создаю.
Я перерыл БД zabbix, но что-то не нашел соответствия.
Плз,помогите, а то для дипломной работы надо :) Zabbix я только начал изучать, так что мог что-то упустить в опсиании проблемы.
спасиб

advice on items settings for items pushed using zabbix_sender

whisky — Wed, 08 Sep 2010 14:07:41 GMT

Hi,

I'm building an asterisk monitoring system, that push events asynchronously to Zabbix using the zabbix_sender protocol (through an Apache Camel routing).

I'm wondering what is the proper settings for thoses items.

question 1) does thoses items type need to be set as 'Zabbix agent (active)' or be 'Zabbix trapper'

question 2) what about the update interval for thoses items that happens asynchronously (i.e item == trigger). Is there is any issue beside graphing units and storage reservation for keeping trend ?

thanks in advance (and thanks for the great book !)

same applications different templates

tekknokrat — Wed, 08 Sep 2010 12:41:47 GMT

Hi,

I gave zabbix 1.8.3, after some absence from monitoring tasks, a try.
For what I see it has a good bunch of new features I need to come common with.
One thing wher I was struggling with, in the past, is that it's still not possible to add the same application to different templates.

Question: what is the idea behind linking applications with templates?

I like the general applications like Memory, File, ... as they are because they
look simple and logical to me.

Example:

When I have a rootserver and e.g. a Virtuozzo Container there is a difference because Virtuozzo don't uses swap space.

So I need to move the swap items/trigger to a new template for explicit Root_Server checks. I want the checks to still appear under the Filesystem application but this does not seems to be possible.

The 2 workarounds I see are to a) rename the Application to Rootserver_Filesystem or b) to move all Filesystem checks from the default Linux_Server Template to explicit Templates.

Solution a) involves a lot more work and in worst case leads to inconsistency of checks. b) seems to be the best way, but using different appnames for different hardware can also move to complex setup.

At all, I don't need apps that offer the same meaning but for different hardware. Any oppinion on that?

Monitoring a non-common-service

ittec — Wed, 08 Sep 2010 10:17:08 GMT

Hi folks

Im having a little trouble here. Few days ago I have installed on some servers open source software to prevent SSH brute force attacks: denyhosts.

I would like to monitor when this "service" is running or not. Denyohsts is a kind of python software (if im not wrong).

When I list processes on server I see:

root 17336 0.0 0.0 140668 5756 ? S 11:45 0:00 python /usr/bin/denyhosts.py --daemon --config=/etc/denyhosts/denyhosts.cfg

I don't know the way to monitor this, because is pyhton itself which is running denyhosts.py daemon. I was thinking on create a new ite;)m with proc.num but I'm not sure of how do it.

Somebody can help me a little with this?

Thanks guys ;)

Clean install and restore no new values?

andydouth — Wed, 08 Sep 2010 08:40:14 GMT

Hi,

We have been running Zabbix fine for 2 years. After our server started erroring on hardware we bought a new server we have installed the 1.8.3 version of Zabbix and restored our old data.

All of the old data is available and viewable from the UI. However we are just not getting any values for the SNMP items we have - When starting the zabbix_server we get the error:

zabbix_server [7570]: Cannot create IPC key for path [./zabbix_server.conf] id [h] error [No suh file or directory]
7570:20100908:000814.570 Cannot create IPC keys for history and trend caches
zabbix_server [7574]: Can not create IPC key for path './zabbix_server.conf', try to create for path '.' [No such file or directory]

If anyone can help - if you have seen this before. Or if you can provide some professional service for us to look over our configuration please let me know.

We are on RedHat 5.3 x64.

Thanks
