Disk Alerts aren't coming or changing web page colors 🔗 link

Hi folks.  For some reason I'm not getting disk full alerts on some servers we have and their webpage screens aren't changing from green to yellow/red.  It was over 95% on the /Volumes/Arena1-EC-D5 disk but not screens changed color and we didn't see an email.

I'm hoping someone can send me some direction on what I should check to see what may be wrong.

Here's the web page disk view for the server:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sdc3             103G  9.3G   88G  10% /
/dev/sdc1             504M   90M  389M  19% /boot
/dev/mapper/mpathip1   21T   18T  2.6T  88% /Volumes/Arena1-EC-D5
/dev/mapper/mpathjp1   21T   16T  4.6T  78% /Volumes/Arena1-EC-D6

Here's a snip from hosts.cfg:

subparent services backupservers Backup Servers
# group-except bbd <font size="+1">Backup Servers</font>

10.1.2.4     CommVault-Media-Agent-MEDAGT02          #CLIENT:MedAgt02.domain.com OS:unix-prod DESC:"SERVER:Comvault Media Agent"

Here's a snip from analysis.cfg:

HOST=CommVault-Media-Agent-MEDAGT02 GROUP=SRMBACKUPS
        PROC cvd
        PROC cvfwd
        PROC cvlaunchd
        PROC EvMgrC
        PROC CvMountd
        DISK /Volumes/Arena1-EC-D5 90 95
        DISK /Volumes/Arena1-EC-D6 90 95
        DISK /boot 92 95
        DISK 85 90

And here's alerts.cfg:

PAGE=services/backupservers SERVICE=disk
script /usr/lib64/xymon/server/ext/html_mail.pl user-af23aeb5b31a@xymon.invalid FORMAT=TEXT RECOVERED DURATION>15m REPEAT=2h
# script /usr/lib64/xymon/server/ext/html_mail.pl user-5eb2bfadc6c6@xymon.invalid FORMAT=TEXT DURATION>30m REPEAT=24h


Thanks much!
