Can Google´s cloud-monitor cause performance issues? - varnish

I think i have a Problem with Googles Cloud Monitoring.
It fires apprx. 20 log per Second and my Server has a big performance problem.
I used varnishlog and varnishncsa to view the logs.
Is there a way to stop the process which is fireing or to deactivate the Cloud Monitoring?

All IP´s are xx´ed and i changed my domainname of course..

I hope Cloud Monitoring doesn't cause issue performance but... it's still in beta :)
From here I know that for use Cloud Monitoring you have installed an agent: I think is a daemon and if you are on Debian based you can stop it from classic /etc/init.d or simple you can unistall with apt-get remove stackdriver-agent command.
Hope this help

AttributeError: object has no attribute 'published' when parsing CNN source

I'm facing this problem since parsing CNN.RSS site. It only get first 7 entries then i get this problem. Below it my log .. Please help me :(. Thanks you
This is my code:
import feedparser
url = "http://rss.cnn.com/rss/edition.rss"
feed = feedparser.parse(url)
for news in feed.entries:
print(news.published)
Log
My log:
https://pastebin.com/vMJSXD0J
To debug this you should first check if published is a part of the keys for news or not.
>>> news.keys()
dict_keys(['title', 'title_detail', 'summary', 'summary_detail', 'links', 'link', 'id', 'guidislink', 'published', 'published_parsed', 'media_content'])
According to this published is a part of the keys for news so your code should work which actually does work.
>>> import feedparser
>>> url = "http://rss.cnn.com/rss/edition.rss"
>>> feed = feedparser.parse(url)
>>> for news in feed.entries:
print(news.published)

How to properly configure grace on Varnish 3.0

I'm trying to configure Varnish to keep into cache for 1 minute a 3rd party page (proxied from a service not under my control).
Unluckily this service sometimes can be down and this transfers troubles to my site; to prevent this I want also to serve from the local cache when the service is not available.
I followed tips from grace and saint mode.
Follow some snippets from my VCL file.
Backend configuration:
backend external {
.host = "external.acme.com";
.port = "80";
.probe = {
.url = "/page";
.interval = 5s;
.timeout = 5s;
.window = 1;
.threshold = 1;
}
}
vcl_recv:
sub vcl_recv {
set req.backend = my_backend;
...
# redirect onto 3rd part service
if (req.url ~ "www.acme.com:80/page$") {
set req.url = regsub(req.url, "(.*)", "http://external.acme.com/page");
set req.backend = external;
}
if (!req.backend.healthy) {
set req.grace = 2h;
} else {
set req.grace = 10s;
}
...
vcl_fetch:
sub vcl_fetch {
if (beresp.status == 503) {
set beresp.saintmode = 5s;
#set beresp.ttl = 1h;
return (restart);
}
set beresp.grace = 2h;
set beresp.ttl = 2h;
if (req.http.host == "external.acme.com") {
set beresp.http.X-Varnish-Action = "Caching external.acme.com";
set beresp.ttl = 1m;
return(deliver);
}
I'm testing the down of the remote service by using iptables and the configuration is working:
Proxy of the remote page is OK
Health polling of the 3rp party page is OK
My only issue is that: when I shutdown the remote service, the 3rd party page is served by the cache for not more than one minute (the TTL configured in vcl_fetch) which is a good TTL for when the remote page is available... but I want to continue to serve this for much longer (2 hours).
This seems in contrast with what I read there: http://book.varnish-software.com/3.0/Saving_a_request.html#req-grace-and-beresp-grace
My suspect is that I'm not entering the grace mode, but the only reason I found on documentation is on not configured health check, but If I look into varnishlog I see health check running properly ("Still healthy", "Went sick", ...)
What I'm missing? There's a way to get what I need?
varnishlog traces

I believe your problem lies on the line return (restart); in vcl_fetch. The restart will force Varnish to process the request from the beginning with a different backend, as you don't have another one this will raise an error. This is the cause that your object is served from the cache for not more than its TTL.
This would be the correct flow:
TTL valid => deliver from cache;
TTL invalid => try to fetch from backend;
Backend not responding => use grace TTL;
Grace TTL valid => deliver from staled cache;
The restart is changing this flow by not letting Varnish get to step 4. Try removing it and see the magic happen.

How to ignore spree redirects in varnish?

I am using varnish on a RoR application. I am getting a redirect loop on the "forgot password" link. I suspect that this is happening due to spree gem (backend). How can I ignore redirects from spree in varnish?
Following is my vcl:
# This is a basic VCL configuration file for varnish. See the vcl(7)
import std;

You can catch the redirect code on vcl_fetch:
sub vcl_fetch {
// ..
if (beresp.status == 307 &&
/* TO-DO: verify that this work better than 'req.url ~ "imagecache"' */
beresp.http.Location == req.url &&
beresp.ttl > 5s) {
set beresp.ttl = 5s;
set beresp.http.cache-control = "max-age=5";
}
// ..
}
You can see it in context on https://github.com/NITEMAN/varnish-bites/blob/master/varnish3/drupal-base.vcl

varnish serve old object during refresh

How can I serve an old object during the fetch of an expired object or max
out connection?
I¹ve configured the grace period in both the vcl_recv as the vcl_fetch.
I even tried to use the saint mode to give me back an ³old² cached object.
Can somebody give me help in this matter?
sub vcl_recv {
# Purge through http
if (req.request == "PURGE") {
if (!client.ip ~ purge) {
error 405 "Not allowed.";
}
ban("req.url ~ " + req.url );
error 200 "Purged.";
}
# Unset all cookies available
if (req.http.cookie) {
unset req.http.cookie;
}
if (req.request != "GET" && req.request != "HEAD") {
/* We only deal with GET and HEAD by default */
return (pass);
}
# Adding Grace period in case backend lags
set req.grace = 3d;
return (lookup);
}
....
sub vcl_fetch {
set beresp.grace = 4d;
set beresp.saintmode = 50s;
set beresp.ttl = 30s;
return (deliver);
}

This is an interesting question.
From DOC
When several clients are requesting the same page Varnish will send
one request to the backend and place the others on hold while fetching
one copy from the back end.
So, at any point in time there will be one client blocked even if you had enabled grace. Grace informs Varnish that you can serve all other n-1 clients with stale content until the first guy comes back with some content to refresh. There is no way to unblock that one guy [technically asynchronous fetch is not possible as such]
Check out this nice article I think what you are actually asking for is a planned feature for next release I hope
