Zabbix Analyse Methods of Monitoring

Type	Advantage	Disvantage	Usage
Zabbix Agent	Low resource usage of host	Potenatial failure of service	Most used OS like Linux and Windows
Zabbix Proxy	Low resource usage on Server of Zabbix	In case of failure we lose tracking of monitoring big part of hosts. Require zabbix Agent In case of installation Proxy on server needs to open new port	Machine with OS of Linux and WIndows Devices which support SNMP
SNMP	Native technology of monitoring ( which is not used any additional plugins)	Complicated structure for begginer	Network Devices Servers with SNMP working
Java Gateway	Monitoring application JMX	Support ony application JMX	Application JMX
Interface IPMI	Monitoring devices which support IPMI	Limited Support	IPMI devices

Zabbix Web Interface

Zabbix Web Interface – Dashboard

Monitoring View
- Dasbhoard (Screens before, we can build dashboard with widgets)
- Problems – where we see problems in more advance mode
- Hosts – List of Machines, VPS etc with status, Latest Data, Problems, Graphs etc
- Latest Data – Infor about EVerything but Last value and last check
- Maps – View mode wheere we can create topologies and graphical view to present
- Discovery – Status of discovery

Zabbix Web interface – Services

please refer to this link: https://www.zabbix.com/documentation/current/en/manual/it_services

Zabbix Web interface – Inventory

The Inventory menu features sections providing an overview of host inventory data by a chosen parameter as well as the ability to view host inventory details.

Zabbix Web interface – Reports

The Reports menu features several sections that contain a variety of predefined and user-customizable reports focused on displaying an overview of such parameters as system information, triggers and gathered data.

–System information

In Reports → System information a summary of key Zabbix server and system data is displayed.

Note that in a high availability setup, it is possible to redirect the system information source (server instance) by editing the ui/conf/zabbix.conf.php file – uncomment and set $ZBX_SERVER, $ZBX_SERVER_PORT to a server other than the one shown active.

With the high availability setup enabled, a separate block is displayed below the system stats with details of high availability nodes. This block is visible to Zabbix Super Admin users only.

Scheduled reports

In the Reports → Scheduled reports users with sufficient permissions can configure scheduled generation of PDF versions of the dashboards, which will be sent by email to specified recipients.

Availability report

In Reports → Availability report you can see what proportion of time each trigger has been in problem/ok state. The percentage of time for each state is displayed.

Thus it is easy to determine the availability situation of various elements on your system.

Triggers top 100

In Reports → Triggers top 100 you can see the triggers that have changed their state most often within the period of evaluation, sorted by the number of status changes.

Audit

In the Reports → Audit section users can view records of changes made in the frontend.

Action log

In the Reports → Audit section users can view records of changes made in the frontend.

Audit logging should be enabled in the Administration settings to display audit records. If logging is disabled, history of frontend changes does not get recorded to the database and audit records cannot be viewed.

Notifications

In the Reports → Notifications section a report on the number of notifications sent to each user is displayed.

From the dropdowns in the top right-hand corner you can choose the media type (or all), period (data for each day/week/month/year) and year for the notifications sent.

Zabbix Web Interface – Configurations

Template groups

In the Configuration → Templates groups section users can configure and maintain template groups.

A listing of existing template groups with their details is displayed. You can search and filter template groups by name.

Host groups

In the Configuration → Host groups section users can configure and maintain host groups.

A listing of existing host groups with their details is displayed. You can search and filter host groups by name.

Templates

In the Configuration → Templates section users can configure and maintain templates.

A listing of existing templates with their details is displayed.

Hosts

In the Configuration → Hosts section users can configure and maintain hosts.

A listing of existing hosts with their details is displayed.

Maintenance

n the Configuration → Maintenance section users can configure and maintain maintenance periods for hosts.

A listing of existing maintenance periods with their details is displayed.

Actions

In the Configuration → Actions section users can configure and maintain actions.

The actions displayed are actions assigned to the selected event source (trigger, discovery, autoregistration, internal actions).

Actions are grouped into subsections by event source (trigger, service, discovery, autoregistration, internal actions). The list of available subsections appears upon pressing on Actions in the Configuration menu section. It is also possible to switch between subsections by using a title dropdown in the top left corner.

After selecting a subsection, a page with a list of existing actions with their details will be displayed.

For users without Super admin rights actions are displayed according to permission settings. That means in some cases a user without Super admin rights isn’t able to view the complete action list because of certain permission restrictions. An action is displayed to the user without Super admin rights if the following conditions are fulfilled:

The user has read-write access to host groups, hosts, templates, and triggers in action conditions
The user has read-write access to host groups, hosts, and templates in action operations, recovery operations, and update operations
The user has read access to user groups and users in action operations, recovery operations, and update operations

Event correlation

In the Configuration → Event correlation section users can configure and maintain global correlation rules for Zabbix events.

Discovery

In the Configuration → Discovery section users can configure and maintain discovery rules.

A listing of existing discovery rules with their details is displayed.

SNMP

#Year 1987 - createion of SGMP - Simple Gateway Management Protocol
It was first protocol for monitor gateway,

Snmp
Protocol has two types of devices:
 - managed
 - manageable

First type of run service call is SNMP which purpose is storage information of state 
of the device

Second type contains manager SNMO which has prupose reading sending values.
*Trap send information from agent to manager  for unexpected behaviour.

MIB
Is database which each element contains value, objects are store in tree hierarchy.
To obtain specific data set it require provide specific code, Structure database MIB is
in documentation RFC 1213.

Specification contains standard database of MIB, call MIB-I, which contains ore than 100
definitions.

1) System objects
2) Interfaces
3) Translation table
4) IP
5) ICMP
6) TCP
7) UDP
8) EGP

Package	Provides
net-snmp	The SNMP Agent Daemon and documentation. This package is required for exporting performance data.
net-snmp-libs	The netsnmp library and the bundled management information bases (MIBs). 
This package is required for exporting performance data.
net-snmp-utils	SNMP clients such as snmpget and snmpwalk. This package is required in 
order to query a system's performance data over SNMP.
net-snmp-perl	The mib2c utility and the NetSNMP Perl module.

SNMP exten by custom Private OID, custom script

It seems that the only way to define a data type for the data is to use the more complex pass or pass-persist directives instead. An example of pass :


#Create file .sh on specific path ~ recommend /etc/snmp/custom_scripts
#!/bin/sh -f
echo .1.3.9950.1.1
echo integer
/bin/systemctl is-active [service] > /dev/null && echo 2 || echo 0


#make file executable
chmod +x [yourscript]

#edit /etc/snmp/snmpd.cond

pass .1.3.9950.1.1 [path_to_script]
#can be custom OID


#restart snmpd
systemctl restart snmpd

#verify 
snmpwalk -Os -v 3 -u [USER]-l authPriv -a sha -A [KEY] -x AES -X [KEY] [IP_HOST] .1.3.9950.1

In this case the script (custom script) is given responsibility for the OID subtree .1.3.9950.1.1, which is within the private OID range . This means that the program you’ve defined is expected to be able to handle iterating over all the OID objects in that subtree (see snmpd.conf man page). In other words the script should implement a SNMP getnext function . It is possible, however, to have a pass program that returns just one static OID object. The above custom script.sh script is a trivial example of that:

Zabbix Agent check – something like snmp walk

#On server of zabbix run this command
zabbix_get -s [IP of AGENT] -p [Port] -k [KEY]
#Example
zabbix_get -s 192.168.10.2 -p 10051 -k proc.num[,mysql]

Zabbix Proxy – jump host

When Firewall blocks access to network or ports
Different Localisation
No VPN access

Advantage of Zabbix Proxy

ProxyOfflineBuffer – Set how long service will be holding the data in case of not accessiblity of Server
Perfomance – Proxy collect data and reduce usage of main server and reduce usage of resource of main server
Monitoirng remote Localisation – Monitoring servers, devices which are in remote locatalization of comapny

#Installation of Zabbix Proxy

Zabbix Reports – Tips for new people

System Informations:
- Check what is running if all is okay etc.
Availability report
- How often there are a problems
Triggers top 100
- Which trigger are lunched the most of time
Audit

Action log
- errors and system zabbix logs

Notifications



Import and Export
You can just export Template or Host configuration and edit it via XML file and upload
again.

Main key is that is faster but requires knowledge of XML.



THere is multiple Agent:
- Zabbix Agent
- SNMP agent
- Agentless - Simple check

1) Go to Confiugration Templates
2) Create TEmplate which will check ICMP (PING)
3) Create new item in new Template
4) Configuraiton of such item
Name : (HOSTNAME) - Failed Ping Check
Type: Simple check
Key: icmpping 
Update interval: 3m
New Application: Availbility 
Add
5) Add new trigger for that item 
Trigger confiugration:
Name: (HOSTNAME) - Failed ping check
Expression: condition 
	- Select item 
  - function max()
   - LAST of (T) 540
   - Result = 0

Backups


#copy content of the /etc/zabbix
rsync  -arvP /etc/zabbix mikurs:/storage/backups/zabbix

#backup mysql
mymysqldump -u root -p  -h localhost  zabbix  | pv   > zabbix_bc.sql
*you need to have install pv


#import
mysql -u root -p [newdatabase of zabbix] < backups.sql

Cluster of Zabbix

1) Raid 1 or 10
2) Virtualzation
3) Use Hyper V (windows) or pacemaker pcs (Linux)

Torn Monitoring

1) Use VPN between locatization
2) Use Proxy
3) Ports - firewall

Worst practise

1) Remove triggers which are often show
2) NOT Archive grapsh, data sets etc
3) Use Akncowledge and assing to resolve the issue - not often used.
4) Not solving the problem
5) Extending time (SLA)

Optimize Zabbix Server

Use SSD

Mysql
- use SSD
- Database on separate hardware
- Use cluster
- Using new and stable database engines
- Separate tables of database on separate drives

#if there is only database base use maximum

#threads open for reading and writing
innodb_buffer_pool_instances = 8

innoodb_log_file_size = 256M
innodb_old_blocks_time = 1000
innodb_io_capacity =  [speed capacity of your drive]
