Transcripción

Zabbix es una herramienta de monitoreo de código abierto a nivel empresarial, que ha sido denominada Elección de los clientes de Gartner por dos años consecutivos. Estamos seguros de que este video de demostración le ayudará a comprender mejor nuestra solución de monitoreo y a obtener una descripción general de sus funciones principales. características y funcionalidades. Le presentaremos tanto la interfaz de usuario como los conceptos básicos de monitorización con Zabbix. Esperamos que disfrutes de esta breve descripción. Bienvenido a la monitorización con Zabbix.

Dashboards

Su punto central de monitoreo en Zabbix será su dashboards. Estos pueden mostrar diferentes datos, problemas, mapas y muchas vistas diferentes. Los paneles se basan en widgets. Estos widgets se pueden personalizar en gran medida y filtrar para que muestren solo los datos necesarios de la forma necesaria para usted. Un ejemplo de un panel de control podría ser un panel de control para su equipo de redes, donde podemos ver descripciones generales de los problemas sobre dispositivos de red, mapas de red y otras cosas relacionadas con nuestra infraestructura de red. Un panel de control completamente diferente puede ser un panel de control para nuestros administradores, donde podemos ver nuestros centros de datos regionales y su estado: ¿Tenemos algún problema con ellos o están bien? A partir de estos mapas, nuestro equipo de gestión podría, por ejemplo, ejecutar algún tipo de script para comprobar la disponibilidad de un centro de datos específico o abrir un submapa, una vista más detallada. de un centro de datos específico: ¿todos los dispositivos funcionan bien o tenemos algunos problemas? Y si es así, ¿qué dispositivo está experimentando esos problemas?

Problemas

Siempre que una métrica recibida coincide con nuestra expresión del problema, también conocida como disparador, creamos un problema en Zabbix. Esto se puede ver en muchas vistas diferentes, por ejemplo, en la sección de problemas o también en nuestros paneles de control. Podemos crear varios widgets diferentes en los paneles que pueden mostrar problemas en diferentes vistas, filtrarlos, etc. Una vez que vemos un problema, podemos abrir un problema específico y echar un vistazo a la descripción general y la información relacionada con el problema: cuándo se creó, cuál fue el último valor relacionado recibido, quién reconoció el problema o tal vez lo cerró manualmente antes. Y también una reseña histórica de los problemas relacionados con el tema específico. trigger expression.

Escenarios Web

Con Zabbix puedes de forma nativa monitorea tu sitio web mediante la creación de escenarios web. Los escenarios web se basan en pasos. Pasos, como realizar un inicio de sesión, verificar si el inicio de sesión se ha realizado correctamente analizando el código de respuesta recibido o buscar una cadena en un sitio web y luego realizar un cierre de sesión. Para cada uno de estos pasos, Zabbix recopilará automáticamente un par de métricas: velocidad, tiempo de respuesta, código de respuesta y si el paso se ha realizado correctamente. Luego, una vez recopiladas las métricas, Zabbix también creará automáticamente gráficos para cada uno de los pasos del escenario web. y el escenario web en su conjunto. Esto le permite analizar el rendimiento de su sitio web en un intervalo de tiempo más largo, observar los problemas creados para estos pasos del escenario web e intentar resolverlos.

Gráficos

Una vez que haya recopilado sus datos, puede visualizarlos utilizando Zabbix Graphs. Estos gráficos son altamente interactivos y pueden colocarse, por ejemplo, en sus paneles de control. Puede pasar el cursor sobre ellos para ver qué datos específicos se recopilaron en un momento específico, o puede ampliarlos en un momento específico. período, o también puede especificar el período de tiempo utilizando la herramienta de selección de tiempo. Allí puede seleccionar uno de los períodos de tiempo predefinidos: "Última semana", "Último mes", usar la herramienta Calendario para seleccionar una fecha específica o usar los campos Desde o Hasta para especificar el período de tiempo para el cual desea mostrar los datos manualmente.

Mapas

Si desea visualizar mejor sus datos, sus activadores o sus hosts, puede utilizar Zabbix Mapas característica para lograr esto. Luego puede colocar este mapa en algún tipo de panel central disponible para los administradores de su red. También puedes vincular otros mapas a un mapa ya existente, creando así una jerarquía de mapas. Luego, puede navegar a través de estos elementos haciendo clic en ellos en el mapa o utilizando el widget del árbol de navegación del mapa para navegar a través de la selección. de los mapas disponibles y navegar a través de ellos de esa manera. Los elementos del mapa también cambiarán sus íconos dependiendo del estado en el que se encuentren. Por ejemplo, un host que no tiene problemas tendrá una marca de verificación verde a su lado. Mientras que un host que tiene algunos problemas tendrá una cruz roja indicando que hay algunos problemas en el host. Esta selección de iconos depende completamente de usted. Puedes cargar tus íconos personalizados y completar tus mapas con ellos.

Acciones

Collecting the data is just the first step. We also have to decide how we're going to react to it. Within Zabbix you can react to your problems, your newly discovered or auto-registered hosts, and also create internal actions, which will notify you when some item, for example, stops working for some reason. Actions are based on and/or conditions. So, it's an and/or logic that you can define. You can define multiple conditions and decide to react, for example, only to problems coming from a specific host group or from a specific trigger based on its trigger name. Once you have defined these conditions, we need to define what we're going to do. And we do it via Operations. You can send a message via email or some sort of integration, or you can also execute remote commands, say, reboot the host if there is a problem on it. You can also decide if we're going to cycle these messages or if we're going to delay the operations. Say, instead of reacting immediately we want to react 30 minutes or 1 hour after the problem has been created, because may be it has a tendency to resolve by itself. We can specify a custom message for each of our operations or we can use the predefined messages for any of the specific integrations that we have defined on our Zabbix instance.

Agente

With Zabbix you also have the option to set up a lightweight agent on your monitoring endpoints. This agent is capable of gathering OS-level metrics, monitor log files, or execute custom scripts, and gather their output as a metric. The agent setup is really simple. You can install it as a package on your Unix-like host or we also have an MSI installer for your Windows machines. The communication between the agent and the server can also go two ways. You can either poll the agent, the server polls the agent passively, or the agent can send traps to the server, and the server can then process them. Starting from version 5.0, you now have the selection between the C-Agent and the Go-Agent. The Go-Agent enables you to monitor many new systems natively out of the box — things such as MySQL or Docker. You can also develop your own custom plugins for the Go-Agent to enable monitoring of any third-party systems that you wish.

SNMP

SNMP monitoring is also fully and natively supported by Zabbix out of the box. We provide SNMP templates for the most popular software and hardware vendors out there. If you wish to create a custom SNMP item, just create a new item and point it towards the Custom OID, and a metric will be obtained from it. You can also automate the process a little bit by using the Low-Level Discovery feature. Just create a new discovery rule and point it towards an OID, on which all of the indexes will be obtained. These indexes will then populate our item prototypes. A new item will be created per index thus automating your SNMP monitoring.

IOT

Zabbix fully supports IoT monitoring out of the box. For this, we offer you two keys modbus.get for Modbus IoT devices and mqtt.get for MQTT devices. To enable this, all you have to do is set up the Zabbix Agent and create a new item that contains your IoT endpoint properties within the key.

Scripts

If you're looking for a more advanced way to gather your metrics, we offer you the script item type. Script item type is based on a JavaScript, script that you can write to monitor any sort of endpoints. Result of the script will be stored as a metric. This can be used to enable synthetic monitoring. For example, you can use the JavaScript to obtain an API token, perform a login with the token, and execute some sort of API call. The result of the call will be stored as a metric.

Java

If you wish to monitor your Java application, Zabbix can also do this out of the box we use JMX or Java Management Extensions technology to connect to your Java application and obtain a list of your MBeans and MBean attributes via your JMX endpoint, which you can specify. We also have some generic out-of-the-box Java templates that you can apply **on** your custom applications.

Ipmi

For more advanced IPMI devices, Zabbix can also connect to their IPMI interface and monitor the different values provided by different sensors on your device. You can either create items for these manually — just provide the sensor name, or you can automate the process by using the IPMI sensor discovery rules. These are provided in out-of-the-box templates within Zabbix. The discovery rule will discover a list of your sensors and based on the item prototype will create a new item for each sensor.

Otros controles: ODBC, ssh, WMI

Besides using the native Zabbix agent checks, SNMP, IPMI, and Java interfaces, we can also use a variety of other methods to gather our data. For example, we can use ODBC checks to connect to your database, execute a query on it, and gather the output of the query as a metric. Or we can use a SSH and Telnet to connect to a remote host, execute a command on it, and gather the result of the command as a metric. On Windows machines, we can, for example, monitor Windows performance counters or use WMI to monitor our Windows hosts.

VMware

When it comes to automation, Zabbix is also natively capable of automatically discovering your VMware environment. We can discover VM guests, hypervisors, clusters, and data stores natively. Based on the type of host that has been created, we will apply the corresponding template that has a list of performance counters that we will be gathering from your VMware environment. You are always free to modify any of these templates to disable or enable a discovery of specific elements or you can always add your own custom performance counters depending on your vCenter version.

Low Level Discovery

Let's imagine a situation where we have multiple similar hosts that are using the same templates, but each of them is not necessarily identical with one another. Let's say that these servers have different file systems. So, how would we solve this issue? We can of course create individual items for each file system on the host, but that's way too much manual labor. Let's say instead of three hosts we have 300 hosts. So, we need to find a way to automate this. And a native way to automate this is to use Low Level Discovery. Low Level Discovery can use any type of check: Agent check, SNMP, ODBC, Java, or whatever else Zabbix supports to automatically discover your entities. And then, based on item trigger and graph prototypes, create items, triggers, and graphs based on the results of the discovery thus automating the creation of these entities in Zabbix.

Trend Triggers

You can natively define your problem thresholds based on absolute time intervals meaning hours, days, weeks, months, or even years. This is enabled by the fact that Zabbix collects hourly trend data, meaning every hour we collect the average minimum and maximum value for each of your collected metric and also the count of collected values for the said metric. With this, you can, for example, create a trigger that will notify you, if the current average load for your application this month is larger than 10 per cent when comparing it with the load last month.

Roles de usuario

In the User Roles section, you have the ability to define new custom User roles. For example, you can create a role for your network admins, your application admins, and your NOC team. Roles are based on User type — either user, admin, or super admin. Based on this type, your roles will be restricted to a subset of specific UI elements, which you can then further restrict or allow. For example, NOC team could have access only to Dashboards and Maps section of the UI. In addition to that, you can also restrict your roles to have access to only specific API methods by using an Allow list or a Deny list. In addition, you can also restrict the execution of specific actions per role. For example, your NOC team won't have the ability to execute scripts or change the problem severity.

Autentificación

If you wish to extend the Zabbix native authentication functionality, you can do so in multiple ways. One of them is LDAP. Just point your Zabbix server towards your LDAP instance, be it AD or OpenLDAP, and you'll be good to go. You can also delegate authentication to your web server backend. Or since version 5.0, you can use SAML. You can configure it natively from within the Zabbix UI in a centralized manner.

External Vault

Zabbix provides robust security options for your user credentials, SNMP communities, and other sensitive data. If you wish, you can store the data in the external vault. In addition, the communication with the Zabbix backend database can also be established via this vault, where all of the credentials will be stored.

Proxy

Imagine a situation, where you have many different data centers all over the world. Each of these data centers has tens of thousands of hosts on them. Each of the hosts has an agent or maybe is being polled by SNMP, and we need to gather the data from all of them. So, I'm already seeing a couple of problems over here. First off — network latency, which will affect our monitoring performance. And also what happens if some part of the network is down and the host is not reachable? In addition, if we're talking about polling, about passive checks, our security team will need to allow all of those connections through the firewall. Well, how can we improve this? There actually is a native way, it's called Zabbix proxies. You can create as many Zabbix proxies as you need all over the world. Let's say you have a proxy in the US, in Asia, and in Europe where your data centers are located.

Media Types

Version 5.0 added many new out-of-the-box integrations. These integrations are implemented by using the new Webhook Media type. Now you have integrations with systems, such as Slack, Jira, Telegram, and many more. These integrations under the hood are based on passing the built-in macro data to a custom JavaScript, which we provide for you. But if you wish, you can always tune it up, change it, and make it fit your specific environment.

Plantillas

As you may have already noticed by now, Zabbix provides a wide variety of different templates for different systems, different software vendors, and templates utilizing different monitoring approaches, such as agent or SNMP. If this is not sufficient for you, you can always navigate to our Zabbix Share — community portal for sharing all things in Zabbix: templates, integrations, anything else that comes to your mind. You can download these and import them in your own environment. Or if you wish, you can contribute — upload your own templates to the Zabbix community share.
