Currently there is no BESClient watchdog or similar IBM provided service/solution for Linux and Unix endpoints.
I have created a bash script that runs via cron to handle some known BESClient situations. However, I would prefer that IBM BigFix to provide a support watchdog solution as part of the product.
Accordingly, I have submitted RFE #109156 requesting that a watchdog service be added to future BES versions for NIX endpoints.
Please review and vote if you think it would help your company too.
