reuse the "found" variable instead (reset it above the while to output and do found += strlen(metrics[i].varnish_name) instead of output = &found[strlen(metrics[i].varnish_name)]
Also a for loop would be good, see below

It should be char *val = found + strlen(metrics[i].varnish_name); here, don't know how it worked before, probably padding or something saved us because strtoull ignore leading spaces.

I'd do for (found = output; (found = strstr(found, metrics[i].varnish_name)); found += strlen(metrics[i].varnish_name)) instead
Please note the extra parenthesis around (found = ... which were missing on the while (thus always evaluating to true because an assignment is always true)

Don't need the else because there is a break, putting output = ... below would be sufficient (see comment above to replace the thing with a for loop anyways).

This is not necessary either because if strstr returned non-null we know there is at least strlen(metrics[i].varnish_name) characters remaining so it's safe to increment the pointer and the loop will just stop by itself once all matches were processed
