Yesterday, a friend of mine asked me how to take all data usage for each Zimbra user for information and reporting purpose. Actually, all information about how many mailboxes usages for each user on Zimbra Mail Server, can be seen on the Zimbra Admin | Server Statistics | Mailbox Quota.
You can see total quota and the quota already in use for each user. Although quite informative, it is not really flexible if we would like to use the data for other purposes. We must re-write the existing information or make a screenshot which will be difficult to be done if Zimbra has a large account.
To resolve this issue, we can utilize Zimbra CLI and then create a small script to find out how many mailboxes and the total quota usage for each user. Here’s an example of the command line :
su – zimbra
zmmailbox -z -m ahmad.iman@excellent.co.id gms
Command Line to see the total mailboxes
su - zimbra zmprov ga vivianchow@excellent.co.id | grep zimbraMailQuota
From the above example, we can create a simple script to looping all user mailbox and retrieve information about mailbox quota
vi /srv/quota-used.sh
paste the following code to the file you just created
#!/bin/bash
echo "Username Total Quota Usage"
zmprov -l gaa | while read ACCOUNT
do
QUOTA_TOTAL=`zmprov ga ${ACCOUNT} | grep "zimbraMailQuota" | cut -d ":" -f2`
QUOTA_USAGE=`zmmailbox -z -m ${ACCOUNT} gms`
echo "${ACCOUNT} ${QUOTA_TOTAL} ${QUOTA_USAGE}"
donegive executable permissions and run by using Zimbra permission
chmod +x /srv/quota-used.sh su - zimbra sh /srv/quota-used.sh
The above script can be modified so that the result can be opened as csv file. Good luck and hopely it can be useful 😀 .
