child pid exit signal Segmentation fault (11)

i saw some threads on google but it seems to be corrected ???

I am wondering if you can define certain windows for thold not to send alerts if they happen. We put our blade center into a restricted state every night for a couple hours to perform backups on the iSeries side and I don't want to alert about the servers that are running on the blades going down and coming back every night between those hours.

I only see the weekend exception check box, but wouldn't it be a bit better if we could define our own schedule for exceptions?

Is there any plugin that can do this?

Thank you!

I'm wondering to create a threshold that is not a fixed value but another data field's value.

I explain it: i.e. I have a Data Template with two Data Fields: InputBytes and OutputBytes; I want to use InputBytes as the threshold, so if OutputBytes is over InputBytes the threshold is triggered. So this threshold would be "dynamic"... is this possible with THold plugin?

It looks like it's all configured correctly, and the thold trips, but I do not get an email. test email works. i do have the email address in the user admin, and it shows on the thold setting for thold i set.

I see the entries in the log file. Something that is odd is that when a thold is breached, that thold does not show in the log file.

Ah, just found something new. I put an explicit email in the thold setting for a device and that one came through, but the default Admin email does not work.

Anyone have any ideas? Same email address in both locations. Something about the mailer code?

Cacti 8.7b on FC8.

I apologize if this is a bit long, but I spent a couple of days trying various solutions mentioned in this forum. It turns out there were a few things I needed to fix, but I have not seen any mention of the final step required to get alerts working. Hopefully I can help prevent some frustration for a few people here.

I have had the same issue with email alerts not being sent when a threshold is triggered, after upgrading to Cacti 0.8.7b with Thold 0.3.9.

I assigned an email address to the admin user in User Management, as suggested by others in this forum. Once I did that, the user name appeared in the list of "Notify Accounts" on the threshold settings page. It was blank before that.

Still did not work. Emails were sent if I added an email address to the "Extra Alert Emails" field, but still would not send to the global account.

I found that when I clicked on the user name (Administrator - Email) in the Notify Accounts field so it was highlighted, then save the settings, it fixed the problem.

Now all my threshold alerts work after highlighting the Notify Account and saving.

Thanks for the tip.

That seemed to help on the threshold breach alert, but i don't get another alert when the breach has cleared.

Anyone else have a suggestion?

Thanks!!

hello,

Is it normal my "Threshold Templates" is empty ?

When i try to auto-create threshold on a device, i got "No thresholds were created."

It seems i need Threshold Templates but i don't know where to find them

I use debian cacti package 0.8.7b-2 and pluginarch patch file cacti-plugin-0.8.7b-PA-v2.1.diff
I installed thold-0.3.9

Thanks.
