Observium Feature分析
最近项目需要一个支持SNMP的Monitoring Software, 于是对比了以下几款软件：

Spiceworks 偏向于IT 管理软件，ipMonitor 最多这能管理50个ports, 所以Observium是比较好的SNMP Monitoring Software.
于是对Observium的功能总结如下，供参考：

Configurable | 1. The dashboard provides a configurable, dynamic front page for Observium. 2. You can Move, Delete or Reload a widget by using the controls which appear when you hover over a widget in editing mode. 3. Widgets can be resized by using the resize handles which appear at the bottom left and bottom right corners of the widget when it is hovered over. 4. Widgets automatically update their data periodically. 5. The placement and order of modules on the front page is defined by a config.php variable. The default includes some useful modules : $config['frontpage']['order'] = array('status_summary', 'map', 'device_status_boxes', 'device_status', 'eventlog'); |

| Devices | All Devices | Basic | - Device - Operating System - Uptime |
1. Observium was designed to auto-discover as much as possible. The auto-discovery process begins by using SNMP to gather information about a device. This information allows Observium to discover all the internal sensors and interfaces of this device. All of these items are required for auto-discovery to work correctly: SNMP must be enabled on your devices and be reachable by Observium - SNMP settings on your devices must match what you have configured in config.php - Access control lists (ACL) on the device must permit the IP of Observium - Devices must return valid, resolvable sysNames. If the sysName - reported by a device is not resolvable, the device won't be added. There are several ways to correct this: Graph DURATION: Last 6 hour Today Yesterday This Week Last Week This Month Last Month This quarter Last quarter This Year Last Year |

| Alerting | Creating Alert Checkers | 1. First of all when you create an alert, you need to choose the 'entity' type that you are building the alert for. Examples of entity types include Port, Device and Sensor. 2. Once you picked the entity type, there's a couple of more things that need to be filled in but these are simple, pick a name for the alert, and pick a message you want to be included once an alert is sent out. 3. The associations pane allows you to define an initial set of rules to match entities to your checker. |
||
| Alert Loging | ||||
| Syslog Alerting | 1. Syslog alerting allows you to generate notifications from syslog messages that are produced by your devices. This allows notification of potential issues which aren't easily detected during the regular poller process, such as OSPF changes, duplicate IP and MAC addresses and configuration changes. 2. Syslog alerting in Observium integrates with the existing contact system, so it allows you to notify via the usual channels, E-mail, ,XMPP, etc. |
|||
| Syslog Rules | 1. Syslog Rules are built using standard PCRE regular expressions. 2 A simple rule to match the word "duplicate" anywhere in the syslog message would look like: /duplicate/ |
|||
| Notification Transports | E-mail Telegram XMPP devnull External Program |
1. By default Observium will attempt to email alerts to the sysContact retrieved from the device via SNMP. If a default email contact has been configured, this will be used for all devices instead. 2. Telegram is a messaging application available for many platforms including iOS, Android, Windows, MacOS and Linux. To use it as a notification transport you need a Telegram account, Telegram Bot and (optional) Group, where this Bot and Account have been added. |
