本文檔介紹與更新失敗相關的警報的識別、故障排除和解決。
思科建議您基本瞭解思科安全電子郵件網關或思科安全電子郵件雲網關。
本文件所述內容不限於特定軟體和硬體版本。
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除(預設)的組態來啟動。如果您的網路運作中,請確保您瞭解任何指令可能造成的影響。
當其中一個掃描引擎的更新失敗了3次或更多次時,將傳送警報。AMP、Case、Graymail、McAfee和Sophos可能會出現失敗的警報。以下是未能成功完成更新的Graymail示例。
The graymail application tried and failed 3 times to successfully complete an update.
要識別此問題,您可以首先確認您仍然收到有關更新失敗的警報。為此,您可以從CLI運行displayalerts命令。
(esa.example.local) (SERVICE)> displayalerts
Date and Time Stamp Description
--------------------------------------------------------------------------------
22 Nov 2024 12:00:00 +0300 The graymail application tried and failed 3 times to successfully complete an update. This may be due to a network configuration issue or temporary
outage.
從這裡開始,您可以從CLI檢視updater_logs,以確認上次故障發生的時間。
esa.example.local (SERVICE)> grep -i "update failed" updater_logs
Fri Nov 22 12:00:00 2024 Warning: graymail update failed
如果上一次故障發生在稍早之前,則可能是由於網路延遲所致,因此可以安全地忽略警報。
您最終可以從CLI運行enginestatus all命令,並確認引擎和規則確實更新成功。請注意,引擎更新頻率低於規則。因此,雖然您可以看到規則上次更新是在最近5-10分鐘內,但是它可能是在引擎上次更新後的幾天或幾週內。
