HTTP template operation

Steps to ensure correct operation of templates that collect metrics with HTTP agent:

1. Create a host in Zabbix and specify an IP address or DNS name of the monitoring target as the main interface. This is needed for the {HOST.CONN} macro to resolve properly in the template items.
2. Link the template to the host created in step 1 (if the template is not available in your Zabbix installation, you may need to import the template's .xml file first - see Templates out-of-the-box section for instructions).
3. Adjust the values of mandatory macros as needed.
4. Configure the instance being monitored to allow sharing data with Zabbix - see instructions in the Additional steps/comments column.

This page contains only a minimum set of macros and setup steps that are required for proper template operation. A detailed description of a template, including the full list of macros, items and triggers, is available in the template's Readme.md file (accessible by clicking on a template name).
TemplateMandatory macrosAdditional steps/comments
Template App Apache by HTTP {$APACHE.STATUS.HOST} - the hostname or IP address of Apache status page (default: 127.0.0.1).
{$APACHE.STATUS.PATH} - the URL path (default: server-status?auto).
{$APACHE.STATUS.PORT} - the port of Apache status page (default: 80).
{$APACHE.STATUS.SCHEME} - the request scheme. Supported: http (default), https.
Apache module mod_status should be set (see Apache documentation for details).
To check availability, run:
httpd -M 2>/dev/null | grep status_module

Apache configuration example:
<Location “/server-status”>
SetHandler server-status
Require host example.com
</Location>
Template App Elasticsearch Cluster by HTTP {$ELASTICSEARCH.PORT} - the port of the Elasticsearch host (default: 9200).
{$ELASTICSEARCH.SCHEME} - the request scheme. Supported: http (default), https.
{$ELASTICSEARCH.USERNAME}, {$ELASTICSEARCH.PASSWORD} - login credentials, required only if used for Elasticsearch authentication.
-
Template App Etcd by HTTP {$ETCD.PORT}- the port used by Etcd API endpoint (default: 2379).
{$ETCD.SCHEME} - the request scheme. Supported: http (default), https.
{$ETCD.USER}, {$ETCD.PASSWORD} - login credentials, required only if used for Etcd authentication.
Metrics are collected from /metrics endpoint; to specify the endpoint's location use --listen-metrics-urls flag (see Etcd documentation for details).

To verify, whether Etcd is configured to allow metric collection, run:
curl -L http://localhost:2379/metrics

To check, if Etcd is accessible from Zabbix proxy or Zabbix server run:
curl -L http://<etcd_node_adress>:2379/metrics

The template should be added to each node with Etcd.
Template App Hadoop by HTTP {$HADOOP.CAPACITY_REMAINING.MIN.WARN} - the Hadoop cluster capacity remaining percent for trigger expression (default: 20).
{$HADOOP.NAMENODE.HOST} - the Hadoop NameNode host IP address or FQDN (default: NameNode).

{$HADOOP.RESOURCEMANAGER.RESPONSE_TIME.MAX.WARN} - the Hadoop ResourceManager API page maximum response time in seconds for trigger expression (default: 10s).
Metrics are collected by polling the Hadoop API remotely using an HTTP agent and JSONPath preprocessing. Zabbix server (or proxy) execute direct requests to ResourceManager, NodeManagers, NameNode, DataNodes APIs. All metrics are collected at once, thanks to the Zabbix bulk data collection.
Template App HAProxy by HTTP {$HAPROXY.STATS.PATH} - the path of HAProxy Stats page (default: stats).
{$HAPROXY.STATS.PORT} - the port of the HAProxy Stats host or container (default: 8404).
{$HAPROXY.STATS.SCHEME} - the request scheme. Supported: http (default), https.
HAProxy Stats page should be set up (see HAProxy blog post for details or template's Readme.md for configuration example).
Template App Nginx by HTTP {$NGINX.STUB_STATUS.HOST} - the hostname or IP address of Nginx stub_status host or container (default: localhost).
{$NGINX.STUB_STATUS.PATH} - the path of Nginx stub_status page (default: basic_status).
{$NGINX.STUB_STATUS.PORT} - the port of Nginx stub_status host or container (default: 80).
{$NGINX.STUB_STATUS.SCHEME} - the request scheme. Supported: http (default), https.
'ngx_http_stub_status_module should be set up (see Nginx documentation for details or template's Readme.md for configuration example).
To check availability, run:
nginx -V 2>&1 | grep -o with-http_stub_status_module
Template App PHP-FPM by HTTP {$PHP_FPM.HOST} - a hostname or an IP of PHP-FPM status host or container (default: localhost).
{$PHP_FPM.PING.PAGE} - PHP-FPM ping page path (default:ping).

{$PHP_FPM.SCHEME} - the request scheme. Supported: http (default), https.
{$PHP_FPM.STATUS.PAGE} - PHP-FPM status page path (default:status).
1. Open the php-fpm configuration file and enable the status page:
pm.status_path = /status
ping.path = /ping

2. Validate the syntax: $ php-fpm7 -t

3. Reload the php-fpm service.

4. In the Nginx Server Block (virtual host) configuration file, add (see template's Readme.md for an expanded example with comments):
location ~ ^/(status|ping)$ {
access_log off;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_pass 127.0.0.1:9000;

Template SAN NetApp AFF A700 by HTTP {$URL} - AFF700 cluster URL address (default: ' ' )
