# NGINX web server

# NGINX web server discovery {#ariaid-title1}

NGINX is an open source web server with a load balancer. Discovery identifies the web server and information related to the load balancer.
Discovery identifies NGINX server software using the following process:

1. The NGINX Process Classifier detects a running process that matches the following criteria during the exploration of a Linux server:
   * Name starts with nginx
   * Name contains master
   {#c_NGINXWebServerDiscovery__ul_izx_hkp_cr}
2. If there is a match:
   * A record is created in the NGINX Web Server \[cmdb_ci_nginx_web_server\] table.
   * A Runs on relationship is created in the CI Relationship \[cmdb_rel_ci\] table for a Linux server (Linux Server \[cmdb_ci_linux_server\]) and for an NGINX web server (NGINX Web Server \[cmdb_ci_nginx_web_server\]).  
     The following two probes are triggered:
     * NGINX -- Version: This probe contains a Bourne shell script. It determines the version of NGINX and populates the NGINX Web Server \[cmdb_ci_nginx_web_server\] table.
     * NGINX -- Get Configuration: This probe contains a Bourne shell script and an argument that determines the path of the NGINX configuration file. The probe identifies configuration parameters based on keywords within the configuration file and returns them as a single payload result.
     {#c_NGINXWebServerDiscovery__ul_djl_lkp_cr}
     The sensor on the ServiceNow instance parses the payload result and populates the CMDB.
{#c_NGINXWebServerDiscovery__ul_osk_jkp_cr}  
You must have the following requirements to discover an NGINX webserver:

* NGINX is installed and running on the server.
* The MID Server has access to the NGINX configuration file, which is /`etc/nginx/nginx.conf` by default.
{#c_NGINXWebServerDiscovery__ul_v3r_xjp_cr}

## Requirements {#c_NGINXWebServerDiscovery__section_ct4_h21_bcb}

For NGINIX servers:

* Ensure that the NGINX software is installed and running on the server.
* Grant the MID Server has access to the NGINX configuration file, which is /etc/nginx/nginx.conf by default.
* Enable secure shell (SSH) commands to identify the following associated elements:  
  * NGINX Version
  * NGINX Get Configuration
  {#c_NGINXWebServerDiscovery__ul_et4_h21_bcb}
{#c_NGINXWebServerDiscovery__ul_dt4_h21_bcb}  
The following probes require execute privileges to run commands:{#c_NGINXWebServerDiscovery__table_fdg_ghb_1t__entry__2}

| Probe | Commands |
|-|-|
| Nginx -- Version | nginx |
| Nginx -- Get Configuration | echo, sed, httpd, cut, grep, egrep (within the Bourne shell script) |
[Tabelle : 1. Commands]

{#c_NGINXWebServerDiscovery__table_fdg_ghb_1t}  
Hinweis:  
The Nginx pattern performs top-down discovery on both Windows and Linux servers. For information on prerequisites for top-down discovery for NGINX web servers, see [Prerequisites for performing top-down discovery using Service Mapping](https://servicenow-prod.fluidtopics.net/zJNM2LOjkPv9A1jxz9Z5bw "Learn about credentials, users, and user permissions you must configure to let Service Mapping access and discover applications inside your organization private network.").

## Probes and Sensors {#c_NGINXWebServerDiscovery__section_ft4_h21_bcb}

Discovery identifies NGINX server software using the following process:

1. The Nginx Process Classifier detects a running process that matches the following criteria during the exploration of a UNIX server:
   * The name of the process starts with nginx.
   * The name of the process contains master.
   {#c_NGINXWebServerDiscovery__ul_ht4_h21_bcb}
2. If there is a match:
   * A record is created in the Web Server \[cmdb_ci_web_server\] table.
   * A Runs on relationship is created in the CI Relationship \[cmdb_rel_ci\] table for the Linux Server \[cmdb_ci_linux_server\] table and the Web Server \[cmdb_ci_web_server\] table.
   {#c_NGINXWebServerDiscovery__ul_it4_h21_bcb}
3. The following two probes are triggered:
   * Nginx -- Version: this probe contains a Bourne shell script. It determines the version of NGINX and populates the Web Server \[cmdb_ci_web_server\] table.
   * Nginx -- Get Configuration: this probe contains a Bourne shell script and an argument that determines the path of the NGINX configuration file. The probe identifies configuration parameters based on keywords within the configuration file and returns them as a single payload result.
   {#c_NGINXWebServerDiscovery__ul_jt4_h21_bcb}
4. The sensor on the ServiceNow instance processes the payload and populates the CMDB.
{#c_NGINXWebServerDiscovery__ol_gt4_h21_bcb}

## Data Collected {#c_NGINXWebServerDiscovery__section_kt4_h21_bcb}

Discovery creates or updates CMDB records when it detects a running NGINX process. The following data is collected. {#c_NGINXWebServerDiscovery__table_g3g_tfb_1t__entry__3}

| Table Name | Field and Label Name | Probe |
|-|-|-|
| Name | cmdb_ci_lb_appl \[name\] | Nginx-- Get Configuration |
| IP Address | cmdb_ci_lb_appl \[ip_address\] | Nginx-- Get Configuration |
| Last Discovered | cmdb_ci_lb_appl \[last_discovered\] | Nginx-- Get Configuration |
| Version | cmdb_ci_lb_appl \[version\] | Nginx-- Version |
| Name | cmdb_ci_lb_pool_member \[name\] | Nginx-- Get Configuration |
| Last Discovered | cmdb_ci_lb_pool_member \[last_discovered\] | Nginx-- Get Configuration |
| IP Address | cmdb_ci_lb_pool_member \[ip_address\] | Nginx-- Get Configuration |

## Relationships {#c_NGINXWebServerDiscovery__section_lt4_h21_bcb}

In the table \[cmdb_rel_ci\] the following relationships are populated:

* The records in the cmdb_ci_lb_appl table run on the cmdb_ci_web_server table records.
* The records in the cmdb_ci_lb_service table use the cmdb_ci_lb_pool table records.
* The records in the cmdb_ci_pool table are used by the cmdb_ci_service table records.
* The records in the cmdb_ci_pool table are members of the cmdb_ci_pool_member table.
* The records in the cmdb_ci_pool_member table are members of cmdb_ci_pool table.
