Graphs:
- new HOST::items which presents number of host items vs number of unsuppoerted item
Items:
- new items with current counter of total host items (supported/unsupprted/enabled/disabled)

(I must remember to change all those URL after merge to master)

non-standard port.
Macros: {$SVC_SSH_PORT}

- interfaces: use iIF-MIB::ifAdminStatus instead IF-MIB::ifOperusStatus on checking if interface is up or down
- interfaces: add to LLD iterator item IF-MIB::ifIndex and map it to {#IFINDEX} macro
- interfaces: add to all items, triggers anf graphs prototypes names [{#IFINDEX}] to display physycal port number in those names

- create item description

PHP-FPM and debian

{$PHPFPM_HOST} -> {$SVC_PHP_FPM_HOST}
{$PHPFPM_PORT} -> {$SVC_PHP_FPM_PORT}
{$PHPFPM_STATUS_URI} -> {$SVC_PHP_FPM_STATS_URI}

…perocess name

even if php-fpm processes are ps command shows working php-fpm processes.

if this trigger is active it may mean as well that macro used by template
needs to be corrected (best in host template macros).

- Graphs:
  - delete SVC::zabbix_server::items/wcache::buffer::pfree graph
  - new SVC::zabbix_server::hosts graph with number of monitored hosts
  - new SVC::zabbix_server::items/triggers graph with total number of items vs. triggers
  - new SVC::zabbix_server::items::nvps graphs with zabbix stack NVPS
- Screens:
  - reorganized SVC::zabbix_server::status screen to put in rows:
    - "process busy %" and "internam process busy %"
    - "cahces usage %" and "vcache::hits/misses"
    - "processing queue" and flame like graph with "queued items"
    - "items totat/unsupported" and "items::nvps"
    - "items/triggers" and "hosts"

  - Triggers:
    - added missing "SYS::Host is down" trigger with all necessary dependencies

 - Triggers:
   - "SYS::Host is downi" corrected descrition

 - LLDs:
   - graphs improvements

  - Triggers:
    - added SYS::Host is down
    - added CPU::idle {ITEM.VALUE}

… items names

OS Linux:
 - Remove duplicated triggers on LLD VOL

Just apply changes in the templates format generated by zabbix 4.2.x
without changing anything in items, trigger etc.

Macro {$HTTP_SERVICE_PROCESS} has bee nadded to allow easy use it on Debian/Ubuntu.
Default value is "http". On Ubuntu/Debian that value needs to be changed to "apache2".

All graphs in screens resolution have been changed to 1200x200 or 600x200
in case screens with two columns of graphs. That resolution is better suited for FHD.

In "SVC::$1 tcp/$3" item remove hardcoded port 80 and add using
{$NGINX_PORT} macro.

Add using "{$HTTP_SERVICE_PROCESS}", "{$HTTP_SERVICE_PORT}" macros in more places in item names and triggers
Rename "net.tcp.service[http,,{$HTTP_SERVICE_PORT}]" key item from "SVC::$1" to "NET::$1"
Rename "SVC::Apache tcp/{$HTTP_SERVICE_PORT} is DOWN" trigger to "NET::Apache tcp/{$HTTP_SERVICE_PORT} is DOWN"

Copy the same set of 6 NET item LLD prototypes as in "OS Linux" template
to cover monitoring in/out traffic in packets and bytes and errors and dropped
packets as well.

Looks like by mistake on rearanging graphs to two columns screen
I've deleted one graph.

This provides exactly tehe same pattern of the macros names as it is already
implemented in "Service php-fpm" template. I'm going to use the same pattern in
all other "Service <foo>" templates.

Provide the same abstraction as in Apache pndhp-pfm templates.
Added {$SVC_NGINX_PROCESS} macro with default value "nginx".
Added note in template description and and README.md athat on using
this template on Debian/Ubuntu {$SVC_NGINX_USER} macro value needs
to be changed to "www-data".

…::{#FSNAME}

Provide per volume grouping metric in "Last data" view list by move
from fixed "VOL" Application to per volume "VOL::{#FSNAME}".
Added "VOL:" LLD items descriptions.

"VOL:" LLD items fixed Application "VOL" changed to per volume "VOL::{#FSNAME}".
"NET:" LLD items fixed Application "NET" changed to per interface "NET::{#FSNAME}".
So now is the same type of view in "Last data" list like on OS Solaris and
IF-MIB templates.

"VOL:" LLD items fixed Application "VOL" changed to per volume "VOL::{#FSNAME}".
"NET:" LLD items fixed Application "NET" changed to per interface "NET::{#FSNAME}".
So now is the same type of view in "Last data" list across all OS and IF-MIB
templates.

…D items.

Replace DSK, NET and VOL Applications used in LLD items prototypes by
DSK::{#DISK}, NET::{#IFNAME} and VOL::{#FSNAME}.

Use README.md format in template description to make easier straight
copy&paste to externel documentation.

Monitoring of those processes is not essential and will be provided
in separated template(s).

…release.

Replace SYS::rh-distribution by SYS::os-release which grabs the content of the
/etc/os-releases using vfs.file.contents[/etc/os-release] key
(this will be wortking on all LSB compliant distributions).
HW::CPU item key changed from system.hw.cpu to system.hw.cpu[,model] because
this option doesws not include current CPU frequency (which is constantly changing).

…ux distributions.

NET::segments retransmitted sed regexp changed to cover old "segments retransmited"

DSK: LLD items Application changed from DSK prototype DSK::{#DISK}

Rewrited VOL triggers to use proper severities and triggers prototypes
dependencies.

Added in "VOL:" LLD filter off all volumes mounted under /var/lib/lxc. If OS Linux
template will used inside of each LXC container it will provide proper not duplicated
monirtoring of the LXC container volumes.

…VALUE} LLD trigger.

Now alarms are raised <1%, <%5, <10% and now <20% free volume space.

Use "^loop.[0-9]" instead "^loop".

… less than 5% or 15% CPU

idle time time for at least 1 hour and alarm is cleared ehen for next hour will be no other
flapping anbove 5% or 15%.

…ices ZFS

vdevs partitions and corrected regexp to remove all SCSI partitions

Remove control caracters.
Fixed sd* SCSI devices partitions.

Add info that now this LLD is able to handle ZFS vdevs.

Added new MEM:: metrics which are now available in zabbix 4.2.x (added by my patch
https://support.zabbix.com/browse/ZBX-13233):
- MEM::active
- MEM::anon
- MEM::inactive
- MEM::slab
Added new graph MEM::active vs inactive.
Added to MEM screen MEM::active vs inactive graph.

Closing https://github.com/kloczek/zabbix-templates/projects/1#card-22419180.

Forgot add in prev commit description about that
"Discard unchanged" filter preprocessor cannot be used for now
https://support.zabbix.com/browse/ZBX-16456 so this is kind of workaround
for that issue.
When dissue with "Discard unchanged" filter on presentation layer will be sorted out
I'm going to change sampling that metrics to 10 or 20 min and even with that
it will be less wrritten data to the database however any live changes meomnory in
containers/namespaces settings will be almost instantly visable in the monitoring data.

…story period=1h

As "Discard unchanged" filter preprocessor cannot be used for now
https://support.zabbix.com/browse/ZBX-16456 this is only temporary
workaround until that issue will be sorted out.

…ible.

Template has been tested on Ubuntu Xenian and Bionic.

CPU::idle trigger now uses macros:
- {$OS_CPU_IDLE}: threshold below which is raised alarm about low
  CPU::idle time
- {$OS_CPU_IDLE_HIST}: hysteresis time for CPU::idle after which alarm
  starts and recovers after additional period defined in {$OS_CPU_IDLE_HIST}
If those macros are not defined in system macros alarms about low CPU::idle time will be not created

- Items:
  - PROC::mysqld
    - change hardcoded MySQL process name to the macro {$SVC_MYSQL_PROC}
    - add "proceses" missing unit
  - "version" add "Discard unchanged with hartbeat" filter which allows
    change sampling rate from 1d to 5min with HB preriod 7d
- Triggers:
  - "SYS::processes::{$SVC_MYSQL_PROC} is not running" severity changed
    to disaster
- Add use md markups in template description

All trigges should not be active when "SYS::Host is down" trigger is active.

Add proper dependency for all trigges which still does not depend on "SYS::Host is down"

Add proper dependency for all trigges which still does not depend on "SYS::Host is down"

and {$NGINX_PORT} to {$SVC_NGINX_PORT}.
Just to keep consistency with other templates.

Fist rule for triggers like:
 - Version has changed
 - Configuration parametr has changed
Assigne them as "Not classified" severity.

…rsion change

Service MySQL:
 - Triggers:
    - change "SVC::MySQL::version has changed to {ITEM.LASTVALUE}" to "Not classified"
Service Zabbix Agent:
 - Triggers:
    - change "SVC::zabbix_agent::version has changed to {ITEM.LASTVALUE}" to "Not classified"

Complete swap space monitoring using LLD, so system swap monitoring
is added only when the monitored system uses swap device(s).
During the implementation of the swap monitoring, I found some
difficulties about which you can read on:
https://support.zabbix.com/browse/ZBX-16821
This is an excellent example of how to add similar things which add
the set of items/triggers/graphs or not depends on the state of some
single resource.

Monitoring of the swap consists of:
- "SWAP:" new LLD
  It adds prototypes:
  - items: "in", "total", "out" and "used" with discard unchanged filter
  - "SWAP" and "SWAP::in/out" graphs
  - trigger: "SWAP::low space ({$ITEM.VALUE}% used)"
    the trigger is activated when more the "{$SWAP_HIGH}" percent of the swap
    is used with default "{$SWAP_HIGH}=80" value
- Screens:
  - "SWAP" added with "SWAP" and "SWAP::in/out" graphs

TODO: add similar modification for L2ARC monitoring and MySQL slave databases
connections.
