答:請參考–英文手冊第 204 頁。

To view Syslog messages in the Web Console:
1. Click Start > All Programs > SolarWinds Orion > Orion Web Console.
2. Log in to the Orion Web Console.
3. Click Syslog in the Views toolbar.
4. If you want to filter your Syslog messages table view by device, select the device to which you want to limit your view in the Network Object field.
5. If you want to filter your Syslog messages table by device type, select the type to which you want to limit your view in the Type of Device field.
6. If you want to filter your Syslog messages table by severity, select the severity level to which you want to limit your view in the Select Severity field.
Note: For more information about Syslog severities, see “Syslog Severities” on page 195.
7. If you want to filter your Syslog messages table by facility, select the facility to which you want to limit your view in the Select Facility field.
Note: For more information about Syslog facilities, see “Syslog Facilities” on page 194.
8. If you want to limit your Syslog messages table to show only messages of a designated type, type the appropriate string in the Message Type field.
9. If you want to limit your Syslog messages table to show only messages containing a designated pattern, provide the appropriate string in the Message Pattern field.
Note: An asterisk (*) is required as a wildcard character, both before and after the pattern string, unless the provided pattern is any of the following:

問:Solarwinds Orion NPM 中的「Syslog Server」可以收集多少資料?有沒有上限?

問:Solarwinds Orion NPM 支援「Interface CRC Error」Alarm 嗎?
答:It is possible. If the deivce mibs has OID for CRC errors, NPM can create an alert for CRC detected. But we will need to use the Universal device poller to poll for the information. Universal device poller is part of Orion NPM installation.

問:Solarwinds Orion NPM 主機應該架設在哪裡?
答:只要監控的對象可以 Ping 得到主機即可。

問:沒有 Netflow 狀況下是否可以做到監控?

答:可以,監控到第二層(Node、Traffic、Event、Alert、Interface)。

問:是否有透過 Mirror 方式來收集?

答:Mirror 方式是設備的 Proxy 功能,Solarwinds Orion NPM 是直接接收監控封包。

問:當網路斷線時是否可以發送簡訊?

答:可以。雖然 Solarwinds Orion 本身並無內建簡訊系統,但可以搭配簡訊系統發送障礙通告,多數簡訊平台皆可透過內部網路來發送簡訊。

問:是否支援 Cisco Router 及 PIX Firewall 的狀態監控?
答:都支援。

問:是否支援 Cisco Router 及 PIX Firewall 的設定變更監控?
答:可透過 NCM 程式,當有人變動設定值時,可發出警告通知。

問:可不可以監控網路架構的變更?
答:可以。藉由 Node 的設定,有綁 IP 的設備在 AB 這段間若有設備被拔除或插入,則 A 或 B 這個 Node 便會發出警訊!
